1. Černý, Miroslav. Vinylové předpolymery - metody přípravy a využití .

Degree: 2012, Brno University of Technology

Teoretická část práce se zaměřuje na blokovou radikálovou polymeraci styrenu, methyl methakrylátu, vinyltoluenu a paramethylstyrenu. Shrnuje současné informace o kinetice a možnostech provedení blokové polymerace. Experimentální část se zabývá přípravou polystyrenových předpolymerů blokovou polymerací s cílem nalezení optimálních podmínek přípravy předpolymerů pro následnou polymeraci do téměř 100% konverze. Hodnoty konverze byly stanovovány gravimetricky a molekulové hmotnosti byly získány na základě viskozimetrických měření pomocí Ubbelohdeho viskozimetru. K předpovědi konverze monomeru v daném čase polymerace byly v experimentální části provedeny simulace zaměřené na závislost konverze na času. Rozdíly mezi skutečností a simulací jsou malé ve většině případů a nalezená podoba výpočtů kinetického chování poskytuje uspokojivé výsledky. V závěru práce byl na základě naměřených dat navrhnut nový postup pro přípravu polystyrenových předpolymerů.; The theoretical part of this thesis is focused on bulk radical polymerization of styrene, methylmethacrylate, vinyltoluene and paramethylstyrene. It summarizes actual informations about kinetics and performance possibilities of bulk polymerization. Experimental part deals with polystyrene prepolymers preparation by bulk polymerization. The aim is to find optimal conditions for prepolymers preparation. Prepolymers should be usable for subsequent polymerization nearly up to 100% conversion. Conversion values were gravimetrically determined and molecular weights were obtained by viskosity measurements, which were realized by Ubbelohde viscometer. In the experimental part, there were performed simulations targeted on conversion dependence on time. The purpose was a prediction of monomer conversion at a given time during polymerization. Differences between reality and simulation were low in most of cases and the found form of kinetic behavior calculations provides satisfying results. In the conclusion of this thesis was suggested a new procedure for polystyrene prepolymers preparation. Advisors/Committee Members: Kučera, František (advisor).
