摘　　要：采用叔丁醇与水构成的复合分散体系,乙酸乙酯为溶胀剂,通过悬浮溶胀聚合的方法合成了接枝共聚物——氯化聚乙烯接枝甲基丙烯酸缩水甘油酯(CPE-g-GMA),考察了分散体系各组分配比,单体、引发剂用量,反应温度、时间等因素对接枝率和接枝效率的影响,并对接枝物的结构进行了红外表征。结果表明,GMA单体可以接枝到CPE主链上,并且在最优聚合条件下接枝率可达37%(接枝效率70%以上)。By glycidyl methacrylate（GMA） grafting onto chlorinated polyethylene（CPE）, the graft copolymer CPE-g-GMA was synthesized via swelling suspension method in a complex dispersion medium which was compound with H2O, ethyl acetate （EA） and tert-butyl alcohol （TBA）. Benzoyl peroxide （BPO） was used as the free radical initiator. And the influences of some essential factors on graft degree and graft efficiency were studied in detail, such as the amount of monomer （GMA） and initiator （BPO） , reaction time and temperature, etc. The structure of the grafted copolymer was characterized by Fourier transform infrared spectrum（FT-IR）. The experimental results show that GMA can be grafted onto the chain of CPE with comparative higher graft degree, which can reach 37% with graft efficiency about 70%.
