摘　　要：刚性有机粒子对聚氯乙烯／氯化聚乙烯共混体系形态和增韧机理的研究周丽玲，吴其晔，杨文君，刘士龙，张漫（青岛化工学院橡胶系青岛２６６０４２）关键词刚性有机填料，聚氯乙烯ＰＶＣ，氯化聚乙烯（ＣＰＥ）形态，增韧机理在共混改性中，弹性体增韧硬质聚氯乙烯（ｎｙＶ...he morphology of PVC CPE blended with rigid organic fillers(ROF)and toughening mechanism were studied by TEM and SEM.The results showed that the obvious toughening effect was obtained by filling ROF to PVC CPE matrix.As a result some fibril formed on the broken surface of samples,and CPE distributed in form of network structure in PVC matrix,and ROF in form of particles.Cold drawing of ROF occured and the brittle-ductile transformation of matrix was observeds when the samples were stretched,so that the toughenss of the blends was increased.
