摘　　要：讨论了以气-固相法制备的高氯化EVA(HCEVA)作为涂料中的成膜物,研究了其涂膜的基本性能,并采用氯化原位接枝在EVA主链上分别接枝甲基丙烯酸甲酯(MMA)和苯乙烯(St)进行改性,得到共聚物HCEVA-cg-MMA及HCEVA-cg-St。性能测试结果表明,其涂膜性能均能达到优良的标准,附着力均能达到1级,耐冲击性50 cm,柔韧性为1 mm,同时接枝产物在普通有机溶剂中的黏度降低,表明其溶解性增加。This paper introduce the properties of high chlorinate EVA coating film, which was prepared by gas -solid phase process. The properties of chlorinated EVA grafting methyl methacD＇late copolymer（ HCEVA - cg - MMA） and chlorinated EVA grafting styrene（ HCEVA -cg- St） , which were prepared by in situ chlorinating graft copolymerization （ISCGC） were discussed. The properties of HCEVA, HCEVA - cg - MMA and HCEVA - cg - St coating films were excellent. The adhesion and flexibility reached grade 1 and impact strength 50 cm. And the viscosity of coating was decreased due to increasing of solubility of the graft copolymer in conventional organic solvents.
