PURPOSE:To obtain an impact-resistant resin compsn. having excellent moldability and heat resistance, by blending a specified compd., a polymer, a plasticizer and a reinforcing filler to a polyester composed of polyethylene terephthalate and a polyarylate. CONSTITUTION:A resin compsn. is obtd. by blending 0.05-10pts. (by weight; the same applies hereinbelow) inorg. nucleating agent having an average particle size of 50mu or below, org. compd. contg. a carboxyl group in the form of a metal salt or high-molecular compd. contg. a carboxyl group in the form of a metal salt (a, 3-30pts. modified polyolefin or modified olefin elastomer (b) obtd. by adding 0.001-10mol% of an alicyclic carboxylic acid or its functional derivative contg. a cis double bond in its ring to a polyolefin or an olefin elastomer, 1-30pts. copolymer (c) composed of 80-99% alpha-olefin and 1-20pts. glycidyl methacrylate or glycidyl acrylate, 0.3-10pts. ester plasticizer (d) and 0-150pts. reinforcing filler (c) with 100pts. polyester composed of 40-97pts. polyethylene terephthalate and 3-60pts. polyarylate. |
