| 摘 要： | 研究了丙烯酸接枝聚丙烯（PP—g-AA）作为增容剂对聚丙烯（PP）／环氧化三元乙丙橡胶（eEPDM）共混体系形态和性能的影响。结果表明，在以PP为连续相而eEPDM为分散相时，PP—g-AA的加入大大提高了两相间的相容性，导致eEPDM分散相的细化；PP—g-AA中的羧基与eEPDM中的环氧基团发生了化学反应，形成了接枝共聚物，降低了PP／eEPDM之间的界面张力，起到了很好的界面增容剂的作用，对共混体系韧性的提高非常有利。

| Abstract: | The blends of polypropylene (PP) and epoxidized ethylene propylene diene rubber (eEPDM) were compatibilized with acrylic acid-grafted polypropylene (PP-g-AA). The epoxy groups in the eEPDM reacted with PP-g-AA to form a graft copolymer which reduced the interfacial tension between PP and eEPDM, leading to a fine dispersion of the latter. Thus the impact performance of the system was well improved. |
