摘　　要：采用溶解度参数原则和混合焓变原则,对聚氯乙烯/聚醋酸乙烯酯共混体系相容性进行了预测,并通过粘度、玻璃化转变温度的分析和显微镜的观察来验证.结果表明,聚氯乙烯和聚醋酸乙烯酯共混体系属于部分相容体系,且相容性与组成有关.The compatibility of PVC/PVAc binary blends was predicted by solubility parameters and mixing enthalpy principle and characterized by some methods such as viscometry, the measured glass transition temperature and polar light microscope. The results demonstrated that the PVC/PVAc blends is a partial-compatibility system,and the compatibility is influenced by the ratio of PVC to PVAc in their blends.
