Abstract

Abstract: Using the high temperature and shearing stress of the extruder, we synthesized the graft copolymer of starch with ethyl acrylate by a simple dry method. The effects of reaction conditions on graft copolymerization were discussed. Grafted starch used as a compatibilizer for the blend system of starch and polyethylene was further investigated. The results indicated that grafted starch as a compatibilizer can improve the mechanical properties of the blend of starch and polyethylene.

Key words: starch, ethyl acrylate, graft copolymerization, compatibility
