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。

Abstract: Polyvinyl chloride(PVC)has been blended with solid stated chlorinated polyethylene(CPE). The dependence of the compatibility of the blends on the mixing methods,chlorine content in CPE has been investigated.The dynamic mechanical analysis results showed that the PVC/CPE blends are partially compatible. The compatibility of the blends increases with increasing chlorine content in CPE and is affected by methods of blending. The CPE having continual segments showed a better compatibility with PVC. The morphology of the blends showed that CPEs are distributed on the surface of the PVC particle in a form of continual network.

Key words: PVC, chlorinated polyethylene, blend, compatibility
