摘　　要：近年来,有关高分子改性研究已引起人们的广泛关注。本文对热塑性塑料聚丙烯和聚乙烯熔融接枝改性的常用单体、提高接枝率的方法、增容作用和接枝物的表征等方面进行了综述。Much attention has been attracted to the modification of polyolefins recently. Modification under melt condition was a suitable way to improve the properties of PP and PE, both of which belong to the thermal-plastic materials. In this paper, the grafting monomers, such as the acrylic acid and maleic anhydride and their derivates were mainly reviewed. The ways of increasing the graft yields and compatibilities, characterization of the polyolefin were also described.
