Abstract
Concentrations of solvent and polymer have been measured using confocal Raman spectroscopy in poly(styrene)-tetrahydrofuran, poly(methyl methacrylate)-tetrahydrofuran, and poly(styrene)-p-xylene systems. Free volume theory parameters have been regressed from the measured concentration data. Model-predicted concentration profiles are in very good agreement with the measured profiles in the case of a highly volatile solvent. For instance, free-volume-model-predicted profiles are in very good agreement in poly(styrene)–tetrahydrofuran system and poly(methyl methacrylate)–tetrahydrofuran system. However, the free volume model is not able to predict entire measured profiles in the case of less-volatile solvent in poly(styrene)–p-xylene system.
