摘　　要：研究了聚氯乙烯（ＰＶＣ）与固相法氯化聚乙烯（ＣＰＥ）的相容性与氯含量、共混方式以及ＣＰＥ链结构的关系。动态力学性能表明ＰＶＣ／ＣＰＥ为部分相容体系，ＣＰＥ中类似ＰＶＣ的链段与ＰＶＣ形成相间过渡层，共混方式影响共混体系的相容程度。透射电镜结果表明ＣＰＥ呈连续网络结构分布于ＰＶＣ粒子表面。共混条件一定时，共混物的抗张强度随相容性的改善而增加。Polyvinyl chloride(PVC)has been blended with solid stated chlorinated polyethy-lene(CPE). The dependence of the compatibility of the blends on the mixing methods,chlo-rine content in CPE has been investigated.The dynamic mechanical analysis results showedthat the PVC/CPE blends are partially compatible. The compatibility of the blends increaseswith increasing chlorine content in CPE and is affected by methods of blending. The CPEhaving continual CH_2CHCl segments showed a better compatibility with PVC. The mor-phology of the blends showed that CPEs are distributed on the surface of the PVC particle inaform of continual network.
