PURPOSE:To obtain a polyester resin composition excellent in dimensional stability, resistance to impact and heat and mechanical characteristics. CONSTITUTION:The objective polyester resin composition is composed of 40-90wt.% polyester (e.g. polybutylene terephthalate), 5-30wt.% modified polyolefin (e.g. a modified polypropylene prepared by graft copolymerization of a glycidyl compound) and 5-30wt.% polyolefin (e.g. poly4-methyl-1-pentene). |
