1. Tso, Nai-Chung. Solvent removal from poly (methyl methacrylate)-toluene solution.

Degree: MS, Chemical Engineering (Engineering), 1984, Ohio University

The effect of carrier gas velocity and the solvent content in the carrier gas on the drying of poly(methyl metha- crylate)-toluene solution was studied by using a Du Pont 951 Thermogravimetric Analyzer and a Perkin-Elmer model 330 spectrophotometer. The solvent evaporation flux was plotted against the average carrier gas velocity and against the value {(Ps-Pg)/Ps}×100%, where Ps is the saturated vapor pressure of toluene at the experiment condition and pg is the vapor pressure of the carrier gas, at different concentrations in the duration of drying. The result shows that the solvent content in the carrier gas and the velocity of the carrier gas have negligible effect on the second stage of drying. Also, the results suggests that the development of a large concentration gradient at the surface of the polymer solution, which is due to the high evaporation flux at the surface, will cause % a skin effect which resists further solvent removal from the polymer solution. And this suggests that we could get to a certain desired concentration at a minimum of time by controlling the drying conditions during the time of drying.
