摘　　要：研究了三元乙丙橡胶/聚丙烯(EPDM/PP)共混型热塑性弹性体的配方组成,探讨了其制备工艺,测定了其力学性能和加工流动性,并研究了其对PP的增韧作用效果。结果表明,所制备的EPDM/PP性能与国外产品相当,且其对PP的增韧效果优于传统的EPDM/PP母料。Formula and processing conditions of dynamic vulcanized ethylene - propylene - diene monomer/ polypropy-lenethennoplastic elastomer (EPDM/PP) were studied. Mechanical properties and flowability of the EPDM/PP and its toughening efficiency to PP were determined. The results showed that the EPDM/ PP was comparable in comprehensive performance to its foreign counterpart, and its toughening efficiency to PP was superior to the conventional EPDM/PP masterbatch.
