摘要: 采用固相法氯化聚乙烯(CPE)对聚氯乙烯/线型低密度聚乙烯(PVC/LLDPE)共混体系进行增容改性。扫描电子显微镜、透射电子显微镜、动态力学分析和力学性能测试结果表明,CPE对PVC/LLDPE共混体系具有很好的增容作用。

Abstract: Solid state chlorinated polyethylene(CPE) was used as compatibilizer for PVC/LLDPE blends. The effects of the composition of blends and the molecular structure of CPE on mechanical properties of the blends were investigated. The mechanism of CPE as a compatibilizer for PVC/LLDPE blends was interpreted by correlating the structure of CPE with morphology of the blends revealed by SEM, TEM and DMA. The experimental results showed that the compatibility between PVC and LLDPE and the mechanical properties of the blends were improved by the addition of CPE.

Key words: polyvinyl chloride, linear low density polyethylene, blend, compatibility, compatibilizer
