Abstract

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
