Abstract:
A thermoplastic polyester resin composition, comprising:70 to 60 parts by weight of a thermoplastic polyester resin; and 30 to 40 parts by weight of a polyolefin elastomer modified by adding 0.05 to 0.4 parts by weight of glycidyl methacrylate to 100 parts by weight of polyolefin elastomer polymerized by using a metallocene catalyst; wherein said thermoplastic polyester resin is polyethylene terephthalate; and wherein said polymerized polyolefin elastomer is ethyleneâ€¢&agr;-olefin copolymer having 5 to 30 wt.% based on the weight of the ethylene, of &agr;-olefin comonomer, and the basic structure of said elastomer is represented by the formula (CH2â€”CH2)nâ€¢(CH2â€”CHRhd m, where R is a side chain represented by the formula (CH3â€¢(CH2)L, where L is 3 to 8 inclusive.
