摘要: 通过掺和各种橡胶聚合物如ABS,MBS和天然橡胶等,使聚氯乙烯((PVC)的低抗冲击强度和难加工性得到改进[1,2].ABS和PVC的共混物具有优异的抗冲击强度、刚性、韧性和耐化学性等.这与两聚合物的组份比、相容性及形态结构密切相关[3,4].将丙烯腈(SAN)共聚单体引人聚苯乙烯((PS)和丁二烯((BR)后,使ABS/PVC具有好的相容性[5].本文对ABS/PVC共混体系的不同共混组份,同一共混条件下的相容性,力学性能和形态结构进行了研究.

Abstract: The results from dynamic viscoelastomer, TEM and others showed that the ABS/PVC blends are partially compatible system.The morphological structure of the blends is indeep dependence on the segment compatibility.The interface between the phases plays animportant role in mechanical property of the blends.
