ABSTRACT The effects of temperature and molecular weight on the polymer dissolution rate were investigated by comparison of the numerical simulation with the experimental observations. The

Fickian diffusion equation was modified to predict the non-Fickian behavior by considering the temperature and concentration dependence of diffusion coefficient for moving (swelling) polymer

films caused by solvent incorporation. The polymer dissolution process was predicted using the polymer chain disentanglement mechanism, founded on the reptation theory. The temperature and

polymer molecular weight dependence of dissolution rate was measured using the laser interferometer technique. As results of simultaion and observations for the dissolution of polystyrenes

in ethylbenzene, the dissolution rate increased with increasing temperature and decreasing polymer molecular weight and there was linear relationship between them in logarithmic scale. The

experimentally determined values of exponent a and b which indicate the dependence strength of molecular weight and temperature on the dissolution rate were very similar to those

theoretically estimated. SIMILAR CONTENT BEING VIEWED BY OTHERS CONFIGURATIONAL HEAT CAPACITY OF VARIOUS POLYMERS ABOVE THE GLASS TRANSITION TEMPERATURE Article 25 November 2021 A COMBINED
