PURPOSE:To obtain a resin compsn. with improved impact resistance by adding a specified amt. of a specified copolymer to a compsn. consisting of a polyester resin, a polycarbonate resin, a graft copolymer and a polyphenylene ether resin. CONSTITUTION:The title compsn. is obtd. by compounding 100 pts.wt. (hereinbelow described as pts.) resin compsn. consisting of 30-70 pts. polyester resin (A) wherein a polyalkylene terephthalate is a main component, 5-28 pts. polycarbonate resin (B), 5-35 pts. graft copolymer (C) obtd. by graft polymerizing one or more arom. vinyl monomers and methacrylate monomer in the presence of a rubbery polymer and 10-45 pts. polyphenylene ether (D) with 2-20 pts. copolymer (E) wherein a polyolefin copolymerized with glycidyl methacrylate is a main chain and a styrene polymer is a side chain and glycidyl methacrylate content in the glycidyl methacrylate-copolymerized polyolefin is 5wt.% or more and less than 50wt.%. |
