摘　要：采用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，考察了单一组分相容剂[相容剂分别为NBR270、NBRP65、CPE和氢化苯乙烯-丁二烯-苯乙烯嵌段共聚物(SEBS)]、复合相容剂(SEBS/NBR和CPE／NBR)及交联程度对HPVC／SBR共混体系相容性的影响。结果表明，使用复合相容剂可明显改善HPVC／SBR共混物的性能；动态硫化在改善共混物力学性能方面起主要作用。

Abstract：A HPVC/SBR blended TPE was prepared by dynamic vulcanization．The effect of the Single compatibilizer(NBR270,NBR P65,CPE and SEBS)，the binary compatibilizers(SEBS/NBR and CPE/NBR)and the crosslink density on the compatibility of HPVC／SBR blend was investigated．The results showed that the mechanical properties were significantly improved by adding binary compatibilizer;and the dynamic vulcanization played an important role in improving the mechanical properties of the blend.
Keywords：HPVC; SBR; dynamic vulcanization; compatibilizer
