Temperature dependence of sorption parameters near Tg for propane in a miscible blend of polystyrene and poly(vinyl methyl ether)

Authors


Abstract

The sorption of propane by 75:25% (w/w) miscible blends of polystyrene and poly(vinyl methyl ether) with different thermal histories was investigated near Tg. The dual-mode sorption model was used to analyze the results. The evidence indicates that the Henry's law constant for states below Tg cannot be smoothly extrapolated from the rubbery state.
