中文摘要:
      采用有机过氧化物硫化体系，通过动态硫化方法制备高聚合度聚氯乙烯(HPVC)/SBR共混型热塑性弹性体，测试共混物硫化胶的力学性能。结果表明，当HPVC/SBR并用比为80/20，过氧化二异丙苯(硫化剂DCP)用量为1.5份时，加入1～3份不同种类的相容剂，可改善共混物的力学性能，其中以氯化聚乙烯(CPE)的作用效果最好；返炼次数对共混物力学性能没有明显影响。
英文摘要:
      The HPVC/SBR blends were prepared by dynamic vulcanization with DCP.The mechanical properties of the blend vulcanizates were determined.The results showed that the improved mechanical properties of blends were obtained when HPVC(80)/SBR(20)，1.5 phr of DCP，and 1～3 phr of different kinds of compatibilizers were used，and the best result was obtained when CPE was used as compatibilizer；and the remilling number didnt have significant effect on the mechanical properties of blends.
