▼ For the preparation of the membranes of the microcapsule systems used here, the functionalized polyacrylamide (PAAm) was synthesized with the monomers acrylamide and N-(3-aminopropyl)methacrylamide (NAPMAAm) by polycondensation. The synthesis reaction of this polyelectrolyte was examined spectrometrically and the polymer was characterized in detail. The capsule membrane was developed by interfacial polymerization of PAAm with an acid dichloride crosslinker and has been followed both rheometrically and tensiometrically. The capsule membrane was examined rheologically and microscopically. The analysis of microcapsule behavior in the electric field was performed in two self-designed capacitors, a homogeneous and an inhomogeneous electric field. In addition, the movement behavior was traced microscopically with mass transfer and evaluated by tracking analysis. The dissertation work was carried out both experimentally and supported by computer-simulations. For the evaluation of the deformation behavior, specifically two programs for video analysis have been written in MATLAB. In cooperation with other working groups of the TU Dortmund the simulatory considerations for both the representation of the electric field lines and potentials as well as the elastometric determination of the network properties of the polyacrylamide membranes took place. Magnetic magnetite nanoparticles were encapsulated to determine their influence on the deformation behavior of the microcapsules. For interfacial polymerization, cationic surfactants have been used to support mass transfer to the interphase. A covalent network was generated and homogeneous membranes were detected. In the CTAB system, the calculated modulus of elasticity is ES = 0,053 ± 0,022 Nm-1, which is about one-third less than the simulated result of ES = 0,086 ± 0,066 Nm-1. The Young's moduli of the DTAB-controlled PAAm membrane are rheologically calculated at ES = 0,098 ± 0,049 Nm-1, which is one-fifth higher than the computer-simulated value ES = 0,077 ± 0,022 Nm-1. That means, according to the present determination of storage and Young's moduli, the elasticities of capsule shells with DTAB and CTAB are of the same order of magnitude. If the Young modulus is calculated from the electrical deformation of the capsule membrane, a value of ES = -0,012±0,001 Nm-1 turns out and this result too is to be expected in the order of magnitude, but is low in comparison with the rheological values. In the membrane system with CTAB the average value of the Poisson ratio v = 0.50 ± 0.13 and therefore confirms the literature assumption of the Poisson ratio v = 0.50. The analysis of the deformation behavior of the immobilized microcapsules in the pendant drop tensiometer revealed that there is both a reversible and an irreversible deformation component in the membrane. The deformations are greater, the higher the applied voltage was in the measuring range between U = 100 V und U = 1250 V. Even if the reproducibility of the deformation behavior of the immobilized polyacrylamide capsules… Advisors/Committee Members: Rehage, Heinz (advisor), Kierfeld, Jan (referee).

▼ The work presented in this thesis represents a combination of laboratory and field experiments designed to explain some field observations I made on some coarse sands in South Australia in 1999: that much of the irrigation water and nutrients applied to the sands under drip-irrigation simply passed through the root zone leaving the crops water-stressed shortly after irrigation events. There was clearly only minimal lateral spread of the water in these coarse sands. However, by applying small concentrations of polyacrylamide or ‘PAM’ in the irrigation water, the crops seemed to do better. Furthermore the timing of irrigation events appeared to be more flexible on the PAM-treated properties. I found this intriguing and saw an opportunity to increase the lateral spread of water in the root zone and thereby increasing the stored volume and residence time of water. By retaining more water in the rootzone, there was potential to save a considerable amount of costly irrigation water, and also improve crop production and quality. With encouragement from my then employer (Elders Pty Ltd) and from Ciba Specialty Chemicals Australia, I undertook to explore my findings in greater detail and to attempt to explain them based on some ‘hard’ (experimental) evidence. Increasing the lateral spread of water under drippers in coarse-textured soils requires water to be retained in the root zone for longer periods during irrigation, but the practical methods for doing this are limited to: • Altering the pore size distribution to create a finer average range of pore sizes, either by compaction or by stabilization of smaller pores using organic matter or additions of clay. • Reducing the wettability of the soil so that less water can be taken in and the soil never becomes saturated. (This of course risks surface runoff and suboptimal placement of irrigation water). • Altering the physical properties of irrigation water (eg. viscosity, surface tension) so that it interacts differently with soil pores and moves through them more slowly. The aim of the research was therefore to evaluate the potential for some commercially available PAMs to reduce hydraulic conductivity and to increase water retention on some drip-irrigated coarse sandy soils of South Australia and Victoria. I worked with two commonly available anionic polyacrylamides, designated PAM-1011 and PAM-135, and measured ponded infiltration in laboratory columns of seven different sandy soils from around South Australia and Victoria. I varied the concentration of the polymer within the range typically used in the field (0, 1 and 10 ppm for PAM-1011; 0, 2.5 and 25 ppm for PAM-135) and I also varied the quality of the irrigation water used to mix the PAM solutions in terms of salinity and sodicity (distilled water, 10 and 20 mmol(+) salt/L, using either sodium chloride, calcium chloride, or both). I measured the effects of PAM on pore-size distribution of one of the sands (by the water retention characteristic), on water repellence of the soils (by measuring water droplet… Advisors/Committee Members: Murray, Rob (advisor), School of Earth and Environmental Sciences : Soil and Land Systems (school).

▼ Modified polyacrylamides with ≅ 0.2 mol % of N,N-dihexylacrylamide and hydrolysis degree from 0 to 25 % were synthesized by micellar copolymerization. The hydrophobic monomer was obtained by the reaction between acryloyl chloride and N,Ndihexylamine and characterized by infrared (IR) and proton nuclear magnetic resonance (1H NMR) spectroscopy. The polymer molecular structures were determined through 1H and 13C NMR spectroscopy and the polymers were studied in dilute and semi-dilute regimes by viscometry, rheometry, static light scattering and photon correlation spectroscopy, at the temperature range from 25 to 55 ºC. The data obtained by viscometry showed that the intrinsic viscosity from the hydrolyzed polymers is larger than the precursor polymers at the same ionic strength. The comparison between the charged polymers showed that the polymer with higher hydrolysis degree has a more compact structure in formation water (AFS). The increase of temperature led to an enhanced reduced viscosity to the polymers in Milli-Q water (AMQ), although, in brine, only the unhydrolyzed polymer had an increase in the reduced viscosity with the temperature, and the hydrolyzed derivatives had a decrease in the reduced viscosity. The static light scattering (SLS) analyses in salt solutions evidenced a decrease of weight-average molecular weight (⎯Mw) with the increase of the hydrolysis degree, due to the reduction of the thermodynamic interactions between polymer and solvent, which was evidenced by the decrease of the second virial coefficient (A2). The polymers showed more than one relaxation mode in solution, when analyzed by photon correlation spectroscopy, and these modes were attributed to isolated coils and aggregates of several sizes. The aggregation behavior depended strongly on the ionic strength, and also on the temperature, although in a lower extension. The polymers showed large aggregates in all studied conditions, however, their solutions did not displayed a good increase in water viscosity to be used in enhanced oil recovery (EOR) processes Advisors/Committee Members: Balaban, Rosângela de Carvalho (advisor), CPF:65946499734 (advisor), http://lattes.cnpq.br/7711521318854102 (advisor).

▼ This work aims to study the influence of two additives, the monomer, acrylamide and its polymer, polyacrylamide, solubilized in microemulsion systems and applied on enhanced oil recovery. By the microemulsion system obtained, it was chosen points into the phase diagram, presenting these compositions: 25%, 30%, 35% C/T; 2% Fo (fixed for all points) e 73%, 68% e 63% Fa, respectively. However, the monomer and the polymer were solubilized in these microemulsion points with 0.1%; 0.5%; 1% e 2% of concentration, ordering to check the concentration influence at the physicochemical properties (surface tension and rheology) of the microemulsion. Through the salinity study, was possible to observe that the concentrations of 1% and 2% of polymer made the solution became blurred, accordingly, the study of surface tension and rheology only was made for the concentrations of 0.1% e 0.5% of monomer and polymer, respectively. By the surface tension study it was observed that how the concentration of active matter (C/T) was increasing the surface tension was amending for each system, with or without additives. In the rheology study, as it increases the concentration of active matter increases both the viscosity of the microemulsion system (SME) with no additive, as the SME with polymer (AD2). After the entire study, it was chosen the lower point of active matter (25% C/T; 2% Fo e 73% Fa), plus additives in concentrations of 0.1% and 0.5% to be used on enhanced oil recovery. Assays were made on sandstone from Botucatu Formation, where after the tests, it was concluded that among the studied points, the point who showed the best efficiency of advanced shift was the microemulsion system + 0.5% AD2, with a recovery of 28% of oil in place and a total of 96,49%, while the other solution with 0.5% of polymer presented the worst result, with 14.1% of oil in place and 67,39% of efficiency of total displacement Advisors/Committee Members: Dantas, Tereza Neuma de Castro (advisor), CPF:07286937391 (advisor), http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783139Z0&dataRevisao=null (advisor).

Poliacrilamidas modificadas com ≅ 0,2 mol % de N,N-dihexilacrilamida e grau de hidrólise de 0 a 25 % foram sintetizadas por copolimerização micelar. O monômero hidrofóbico foi obtido pela reação entre cloreto de acriloíla e N,N-dihexilamina e foi caracterizado por espectroscopia no infravermelho (IV) e ressonância magnética nuclear de próton (1H RMN). As estruturas moleculares dos polímeros foram determinadas através de espectroscopia de RMN 1H e 13C e os polímeros foram estudados em regime diluído e semidiluído por viscosimetria, reometria, espalhamento de luz estático e espectroscopia de correlação de fótons, na faixa de temperatura de 25 a 55 C. Os dados obtidos por viscosimetria mostraram que as viscosidades intrínsecas dos polímeros hidrolisados são maiores que a do polímero precursor na mesma força iônica e a comparação entre os polímeros carregados mostrou que o polímero com maior grau de hidrólise tem uma estrutura mais compacta em água de formação sintética (AFS). A elevação da temperatura induziu um aumento na viscosidade reduzida dos polímeros em água Milli-Q (AMQ). Em solução salina, apenas o polímero neutro apresentou aumento na viscosidade reduzida com a temperatura, enquanto os derivados hidrolisados apresentaram uma diminuição na viscosidade reduzida. A partir do espalhamento de luz estático (SLS), em meio salino, foi evidenciada uma diminuição da massa molar ponderal média (⎯Mw) com o aumento do grau de hidrólise, que foi atribuída à redução das interações termodinâmicas entre polímero e solvente, o que pôde ser deduzido pela diminuição do segundo coeficiente do virial (A2). Os polímeros apresentaram mais de um modo de relaxação em solução, quando analisados por espectroscopia de correlação de fótons, e esses modos foram atribuídos a cadeias isoladas e a agregados de diversos tamanhos. O comportamento de agregação dependeu fortemente da força iônica, e também da temperatura, embora de uma forma menos pronunciada. Os polímeros apresentaram grandes agregados em todas as condições estudadas, contudo, suas soluções não mostraram um bom aumento na viscosidade da água para serem usados em processos de recuperação melhorada de petróleo (EOR)

Modified polyacrylamides with ≅ 0.2 mol % of N,N-dihexylacrylamide and hydrolysis degree from 0 to 25 % were synthesized by micellar copolymerization. The hydrophobic monomer was obtained by the reaction between acryloyl chloride and N,Ndihexylamine and characterized by infrared (IR) and proton nuclear magnetic resonance (1H NMR) spectroscopy. The polymer molecular structures were determined through 1H and 13C NMR spectroscopy and the polymers were studied in dilute and semi-dilute regimes by viscometry, rheometry, static light scattering and photon correlation spectroscopy, at the temperature range from 25 to 55 C. The data obtained by viscometry showed that the intrinsic viscosity from the hydrolyzed polymers is larger than the precursor polymers at the same ionic strength. The comparison between the charged polymers showed that the polymer with…

▼ Modified polyacrylamides with ≅ 0.2 mol % of N,N-dihexylacrylamide and hydrolysis degree from 0 to 25 % were synthesized by micellar copolymerization. The hydrophobic monomer was obtained by the reaction between acryloyl chloride and N,Ndihexylamine and characterized by infrared (IR) and proton nuclear magnetic resonance (1H NMR) spectroscopy.

The data obtained by viscometry showed that the intrinsic viscosity from the hydrolyzed polymers is larger than the precursor polymers at the same ionic strength. The comparison between the charged polymers showed that the polymer with higher hydrolysis degree has a more compact structure in formation water (AFS). The increase of temperature led to an enhanced reduced viscosity to the polymers in Milli-Q water (AMQ), although, in brine, only the unhydrolyzed polymer had an increase in the reduced viscosity with the temperature, and the hydrolyzed derivatives had a decrease in the reduced viscosity. The static light scattering (SLS) analyses in salt solutions evidenced a decrease of weight-average molecular weight (⎯Mw) with the increase of the hydrolysis degree, due to the reduction of the thermodynamic interactions between polymer and solvent, which was evidenced by the decrease of the second virial coefficient (A2). The polymers showed more than one relaxation mode in solution, when analyzed by photon correlation spectroscopy, and these modes were attributed to isolated coils and aggregates of several sizes. The aggregation behavior depended strongly on the ionic strength, and also on the temperature, although in a lower extension. The polymers showed large aggregates in all studied conditions, however, their solutions did not displayed a good increase in water viscosity to be used in enhanced oil recovery (EOR) processes Advisors/Committee Members: Balaban, Rosângela de Carvalho (advisor), CPF:65946499734 (advisor), http://lattes.cnpq.br/7711521318854102 (advisor).

▼ When conventional materials are fabricated on the nano-scale, many physical properties of the materials are changed by the length scale at 1 to 20 nm. If at least one of the dimensions is smaller than the length scale of some property, that property is confined and behaves differently from the larger dimensional states. Polymer nano-particles offer an ideal system for the study of the confinement effects on the glass transition (Tg) because the Tg of polymers describes a cooperative motion at the length scale of 10 - 20 nm. The glass transition is one of the most intriguing puzzles in the physics of condensed matter, the study of which will ultimately influence different fields, in particular biophysics and biochemistry. Single molecule chain polymers occupy nano-space. The understanding of the effects of this confinement is limited at present. For example, although there are many studies of the glass transition behaviour of polymers in confined environments, e.g. in ultra-thin films, in pores and near surfaces, the experimental results are controversial even for thin films - the simplest confined geometry. In this study spherical monomolecular polymer particles were prepared by a novel application of spray-drying. The spray-drying process is a classic example of the use of heat and mass transfer fundamentals. The focus of this study was the characterization of the particles produced by spray-drying the water soluble polymers poly(N-vinyl pyridine) (PVP) and polyacrylamide (PAL). The morphologies and glass transition behaviour of these fine particles were investigated by thermal analysis (DSC) and atomic and electron microscopies (AFM, SEM). The diameters of the particles were measured as 50 - 80 nm for PAL, (M̄w = 1.8 x 10[to the power of seven] kg kmol-1) and 14 - 16 nm for PVP (M̄w = 1.3 x l0[to the power of six] kg kmol-1). Calculations show the diameters of the sprayed particles are similar to the dimensions of single chain molecules for both polymers. The AFM images of the PVP show a honeycomb-like structure with a central particle surrounded by six or seven other particles. The glass transition temperature of the PVP single chain nano-particles is ~3[degress celsius] higher than that of the bulk polymer, as shown by normal DSC. An exothermic peak immediately after the glass transition was observed and explained as being due to the energy associated with the interaction of the mesophase structure with its immediate matrix. The high pressure DSC results indicate a lack of plasticisation even though there is a high CO2 sorption. An explanation using a combination of peak area and fictive temperature data is presented. The PVP nano-particles, with their high surface area to volume ratio, are sufficiently compact that the CO2 is adsorbed, but there is little or no permeation of the gas molecules into the monomolecular spheres. This is in contrast to what happens in the bulk film sample.

▼ Polyacrylamide gel electrophoresis (PAGE) was used to study the inheritance of esterase isozyme (EST) phenotypes in Allium fistulosum L. Three A. fistulosum specific loci were identified from the most anodal zones of acitivity, EST-1, EST-4, EST-6. Each locus was found to have two alleles. Both EST-1 and EST-4 encode a null allele. Plants homozygous for the nuli atieies lacked expression of the respective band on the PAGE gel. Starch gel electrophoresis was used to study the inheritance of the Phosphoglucoisomerase (PGI) phenotype. Pgi-1 in A. fistulosum has two alleles, Pgi-1^, and Pgi-1'*. Goodnessof-fit of these alleles to Mendelian ratios was tested in an F2 population with the chi-square statistic. Linkage analysis was also conducted befr.vscn the new alleles presented in this report and with previously identified alleles of ADH, 6-PGDH, and PGM. An incongruity model is presented as a possible expiaiiaiiun for an anomaly in the germination and establishment percentages, as well as a distorted isozyme segregation pattern, observed in F2BG3 seed of an A. cepa x A. fistulosum interspecific hybrid. The F1BG3 parent expressed Pgi-1^, PGI alleles of both species; Pgi-1^ coming from A. cepa (Ac) and Pgi-1^ allele from A. fistulosum (Af). Data collected on the F2BG3 progeny population were percent germination and establishment, segregation of Ac and Af Pgi-1 alleles, and viability and genotype of non-germinated seed, seed that was not planted, and isolated embryo and endosperm tissue. Seed, embryo, and endosperm tissues exhibited 100% viability, despite lower germination and establishment peicentayes.. A pooled goodness-of-fit test of the segregation of Pgi-1 alleles in the populations to the expected Mendelian 1:2:1 ratio using the chi-square statistic gave a x^ = 185.9, well beyond the accepted limits at 2 degrees of freedom, and the 1:2:1 ratio was rejected. Another pooled chi-square goodness-of-fit test of the segregation of Pgi-1 alleles in the populations to a 1:1 ratio based on the incongruity model gave a x^ = 0.203, within the accepted limits at 2 degrees of freedom and the 1:1 ratio was not rejected. Chi-square tests of data from other populations reporting similar to PGI isozyme distortion suppoit the hypothesis.

▼ Polyacrylamide is widely used as a flocculant but the influence of the molecular mass distribution upon flocculant activity is poorly understood. This thesis outlines the successful characterisation of ultrahigh molecular mass polyacrylamide solutions in terms of discrete solvated polymer coils and coil agglomerates. These features were correlated with the observed flocculation, demonstrating a number of solution state features required to improve flocculation activity.Aqueous solutions of polyacrylamide exhibit time-dependant behaviour affecting viscosity and polymer agglomeration. Improving the solvation of the polymer suppressed the agglomerates, as did manipulation of hydrogen bonding through the presence of salts. Limiting agglomeration through improved solvation apparently lowers a barrier to polymer interaction, such that the coils disperse but become more susceptible to reagglomeration under mild shear. These solvent modifications did not fully suppress the agglomerates.To fractionate polyacrylamide into a molecular mass distribution, flow field-flow fractionation (flow FFF) was chosen, coupled to a multi-angle laser light scattering (MALLS) photometer and a differential refractometer for molecular mass and concentration sensitive detection, respectively. For the first time, the analysis of high molecular mass polyacrylamides in water using the flow FFF-MALLS technique has been reported. However, a number of difficulties needed to be overcome, including shear artefacts, sample agglomeration and polymer-membrane interactions.Both polyacrylamide standards and commercial flocculants were amenable to the technique. Commercial flocculants were found to vary not only with regard to viscosity and mean molecular mass, but also with sub- and supramicron size agglomerates. The flow FFF technique is size-sensitive, which for some low molecular mass samples displayed an unusually wide elution profile, in apparent conflict with the molecular mass sensitive MALLS detector. It was concluded that polyacrylamide in solution exists simultaneously in three states: discrete polymer coils, entanglements of a several coils, and agglomerates with supramicron diameters.This thesis concluded with a comparison between the characterised polyacrylamides and observed flocculation activity on a standard kaolin substrate. Results show polymer with supramicron agglomerates produce the largest and most shear-resistant kaolin aggregates with a definite optimum agitation intensity. Higher molecular mass flocculants with less agglomeration bind fine particles under more gentle conditions but are deficient under increasing stress. Flocculants exhibiting coil entanglements showed poor activity and formed only small aggregates. A modified flocculation mechanism was proposed, in which supramicron polymer agglomerates play a critical role.

▼ Conventional barrier methods of erosion control, in particular the silt fence, have demonstrated poor performance at trapping clays and fine silts due to inadequate detention time for settling. Trapping efficiency can be improved by flocculation of clays into larger particles with higher settling velocities. Studies have shown that clay flocculation can be induced by anionic polyacrylamides (PAM) in conjunction with divalent cations. Although anionic PAM is available commercially with different charge densities and molecular weights, the flocculation characteristics of a given anionic PAM are not the same for all soils. The purpose of this study was to investigate the flocculation characteristics of three anionic PAMs on the silty clay loam soil. Jar test experiments were conducted to treat the sediment with PAM and divalent cations. Flocculation efficiency and suspended solid concentration (SSC) were determined with the experimental protocol developed. Specifically, a sequential experimental approach was implemented to determine the (a) PAM type and concentration, and (b) calcium ion concentration that produce high flocculation efficiency and %SSC reduction. The three PAM flocculants considered in this study (PAM10, PAM20 and PAM30) produced the same flocculation characteristics for the silty clay loam soil. PAM played a much more vital role in increasing flocculation efficiency and reducing the suspended solid concentration than did CaCl2 (exchangeable cations). The effective operating range for PAM and CaCl2 concentrations for desired flocculation efficiency and %SSC reduction were found to be 0.05-5 ppm and 1.5-3.5 mmole, respectively. There was a threshold limit after which the flocculation efficiency and %SSC reduction decreases with increase in PAM concentration. This supports the statement: "Application rates of anionic PAM above those suggested by the manufacturer will not provide additional effectiveness." Advisors/Committee Members: Gasem, Khaled A. M. (advisor), Barfield, Bill J. (committee member), Stevens, Ellen W. (committee member), Robinson, Robert S., Jr. (committee member), Warde, William D. (committee member).
