摘　　要：研究了聚丙烯接枝超支化聚(酰胺-酯)(PP-HBP)对聚丙烯/聚氯乙烯(PP/PVC)共混体系力学性能的影响。结果表明,在PP/PVC(质量比为70/30)共混体系中加入5份PP-HBP时,共混物拉伸强度和冲击强度均出现最大值。扫描电子显微镜(SEM)研究结果证明,PP-HBP增强了PP/PVC的界面粘结作用,减小了共混体系的相分离程度。The effect of polypropylene (PP) grafted with hyperbranched poly (amide-ester) (HBP) on mechanical properties of polypropylene/poly (vinyl chloride) (PP/PVC) was examined. The results showed that the tensile strength and impact strength of blends reached the maximum value when the content of PP-HBP was 5phr. The scanning electron microscopy (SEM) indicated that the adhesion at the interface could be enhanced by PP-HBP and the phase separation of PP/PVC blends could be reduced.
