Abstract:
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 methacrylate 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.
Key words:
EVA( ethylene-vinyl acetate copolymer ),

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 50cm，柔韧性为 1mm，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。
