摘　　要：聚合物共混物脆韧转变性能研究Ｖ．橡胶粒子的分布对聚氯乙烯／丁腈橡胶共混物韧性刚性关系的影响刘浙辉朱晓光张学东漆宗能（中国科学院化学研究所工程塑料国家重点实验室北京１０００８０）蔡忠龙（香港理工大学应用物理系香港九龙）王佛松（中国科学院北京...The effect of rubber particle dispersion on the toughnessmodulus relationship of polyvinyl chloride (PVC)/nitrile rubber (NBR) blends is studied. It is demonstrated that the pseudonetwork morphology is much more effective in the rubber toughening of PVC than that of welldispersed rubber particles. However, the rubber particle dispersion does not affect the tensile modulusrubber volume fraction relationship of the blends.The effect of rubber particle dispersion on the toughnessmodulus relationship of PVC/NBR blends are compared. It is concluded that the pseudonetwork morphology is very efficient in generating PVC/rubber blends simulataneously with high toughness and high stiffness.
