| 摘 要： | 利用ＤＳＣ等方法，研究了ＰＶＡ－ＣＳ二元共混体系的相容性。结果表明，ＰＶＡ与ＣＳ之间存在一定的相互作用，为部分相容体系。以Ｆｌｏｒｙ－Ｈｕｇｇｉｎｓ的高分子溶液理论为基础，通过Ｗｏｏｄ或Ｆｏｘ方程，计算出不同共混比的ＰＶＡ－ＣＳ共混体系两相中二组分的表现质量分率，进而计算出体系的聚合物－聚合物Ｆｌｏｙ－Ｈｕｇｇｉｎｓ相互作用参数χ＿（１２）或ｇ＿（１２），对ＰＶＡ－ＣＳ共混体系的相容性进行了验证。

| Abstract: | 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. |
