摘　　要：采用动态硫化法制备了聚氯乙烯(PVC)/氯化聚乙烯(CM)热塑性弹性体(TPE),并对其力学性能和微观相结构进行了研究。结果表明,动态硫化PVC/CM型TPE的拉伸强度及撕裂强度均随PVC含量的增加而提高,当PVC质量分数低于40%时,其应力-应变曲线呈现出典型的弹性体特征;PVC/CM的共混比为60/40时,所制备的TPE表现出了良好的综合性能;CM分散相粒径在10μm以下且较均匀地分散于PVC基体中。The polyvinyl chloride(PVC)/chlorinated polyethylene(CM) thermoplastic elastomer(TPE) was prepared by dynamic vulcanization,the mechanical properties and the morphology of the phase structure of the prepared PVC/CM TPE were investigated.The results showed that the stress-strain curves of the PVC/CM TPE showed the obvious elastomer behavior when the PVC content in TPE was 40% below.Considering the proper elasticity,strength and low hardness,the weight ratio of PVC/CM blend should range from 20/80 to 40/60.Th...
