【摘要】 本文用三种丙烯酸酯弹性体ACR-Ⅰ-3,ACR-Ⅱ-3和ACR-Ⅲ-2,分别与聚氯乙烯(PVC)共混,对PVC/ACR共混体系的形态结构与冲击性能的关系,借助于粘弹谱仪、电子显微镜和旋转粘度计进行了较系统的研究。结果表明,PVC/ACR是部分相容体系,ACR粒子分散在PVC连续相中;当ACR含量为8～10％,粒径为0.6～1.2μ时,PVC/ACR共混物的冲击性能最好。更多还原

【Abstract】 The compatibility of the Poly (vinyl chloride) (PVC) blends with acrylic elastomer (ACR) has been studied by a dynamic mechanical viscbelastometer and a rotational vis-cometer.It is indicated that the PVC/ACR blends are two phase system and there is a definite interaction between PVC and ACR.The phase structure of the PVC/ACR blends has been elucidated by transmission electron microscopy (TEM) and scanning electron microscopy (SEM).It is shown that ACR is dispersed as a particle in the PVC phase.The relation of structure and property for PVC/ACR is discussed.更多还原
