摘要

A series of vinylidene chloride (VDC) copolymers with methyl acrylate (MA) or butyl acrylate (BA) as comonomer (not more than 10%) was prepared by free-radical suspension copolymerization. The effects of comonomer structure, copolymer composition, and reaction condition (such as polymerization temperature on crystallinity) and thermal properties (such as melting temperature and decomposition temperature) were investigated. All VDC/acrylics copolymers studied here are semicrystalline and have more than one crystalline structure. The melting temperature of MA/VDC copolymers is decreased progressively with increase in MA content. The decomposition temperature of MA/VDC copolymers is slight increased gradually with increase in MA content. MA/VDC copolymers have lower melting temperature compared with BA/VDC copolymers with same VDC composition. The melting temperature of VDC copolymers increases with increase in polymerization temperature and decomposition temperature of those is almost independent of polymerization temperature.
