STUDIES ON COMPATIBILITY OF POLY(VINYL ALCOHOL)-CHTTOSAN BLENDS

Wu Liguang;Liu Moe;Zhu Changluo(Department of Chemical Engineering, Zhejiang University,Hangzhou)  
Compatibility of PVA-CS blends has been investigated by mean of differential scanning calorimetry in this paper.Blends were prepared by solution casting with weight fractions of PVA in the blends varying from 0.90 to 0.10.From the measured glass transition temperature(T_g), apparent weight fractions and apparent volume fractions of PVA and CS components in the PVA-rich phase and CS-rich phase of PVA-CS blends were calculated by Wood or Fox relation, and Flory-Huggins polymer-polymer interact ion parameter were determined.The results show that PVA-CS blend is a part-compatibility system.
