摘　　要：采用溶液法将极性单体马来酸酐在隔氧条件下对聚丁二烯进行接枝,通过氢化反应及马来酸酐与端羟基PMMA的酯化反应,合成了氢化聚丁二烯/聚甲基丙烯酸甲酯接枝共聚物。考察了反应时间等因素对接枝反应的影响,测定了聚合物的接枝率,同时对其结构进行了表征。结果表明,所合成的接枝共聚物具有良好耐热性和表面迁移特性,适合用作PP的大分子表面改性剂。Polar monomer MA was grafted onto polybutadiene in the presence of nitrogen by means of solution method, and a macromolecular surface modifier, the copolymer of hydrogenated polybutadieue grafted with poly （methyl methylacrylate） （HPB-g-PMMA） was synthesized by hydrogenation and esterification of polybutadiene with TSH and hydroxyl-terminated poly （methyl methylacrylate）. The effects of the reaction time and other conditions on the graft reaction were studied, the graft efficiency was determined and graft copolymer was characterized. The resuits indicated that HPB-g-PMMA had good heat resistance, could diffuse preferably onto the surface of blends and be used as surface modifier for PP.
