摘　　要：以聚乙烯(PE)为原料,采用氯化原位接枝方法合成以氯化聚乙烯(CPE)为骨架、聚甲基丙烯酸甲酯(PMMA)为支链的接枝共聚物(CPE-g-MMA)。通过IR、GPC、DSC、接枝参数及力学性能的测试,表征了共聚物的结构和性能。结果表明,接枝共聚物结构具有短支链、多支化点的特点。其接枝共聚物与相同氯含量的CPE相比,在力学性能方面有显著提高。A grafted copolymer （ CPE-g-MMA ）, composed of poly （ methyl methacrylate ） （ PMMA ） as branched chains and chlorinated polyethylene（CPE） as backbone was synthesized by in-situ chlorinating graft copolymerization based on HDPE. It was characterized by FF-IR, GPC and DSC. The graft parameters and mechanical property of the polymer were measured. The graft chains are short and there are much more graft chains on the backbone chains. The results show that the graft copolymer obtained by in-situ chlorinating has good properties.
