Abstract

A new mathematical model based on configurational entropy and Flory-Huggins theory, to predict the glass transition temperature, Tg of miscible polymer blends, was presented. The new model predicts the Tg dependence of blend composition for the cases of maximum behavior with positive deviation and linear additivity obeying the Fox equation. The strength of specific interaction in each system can be compared easily with the model. The results show that the polymer blend is able to form a miscible phase between the carbonyl of poly(vinylpyrrolidone) (PVP) and the hydroxyl of poly(vinylphenol) (PVPh).
