摘要: 如何解决废弃塑料制品的再资源化和使用无污染的降解塑料是当今人类急待解决的热点课题.淀粉与丙烯酸甲酯(MA)进行接枝共聚以制备塑料发泡产品的研究已有报道[1~3],一般认为塑料中淀粉含量在40%以上的产品,很容易在土壤中被微生物降解掉[4].

Abstract: The graft copolymerization of starch and methyl acrylate(MA) in three differentreaction systems, MA-CH3OH-H2O, aqueous solution, emulsion system has been carriedout.The composition of the grafted PMA in copolymer and homopolymer PMA, the viscosity-average molecular weight of the graft copolymer, the graft efficiency and freqency and themicrostructure and mechanical property have been investigated.The biodegradable graftplastics with 60% starch was obtained.

Key words: starch, methyl acrylate, graft copolymer, biodegradable plastics
