Abstract

Abstract: Toughened polybutylene terephthalate(PBT) was prepared by blending with self-made ethylene-methyl acrylate-glycidyl methacrylate terpolymer and a commercial toughening agent. Notched impact strength, elongation at break, and melt flow rate were tested. It showed that toughening effect was the best when the grafting degree of ethylene-methyl acrylate-glycidyl methacrylate terpolymer was 1.96 %, and its content in PBT was 15 %. The notched impact strength and the elongation at break of the toughened PBT increased by 65 % and 30.6 %, respectively.
