PURPOSE: To provide the titled compsn. which has excellent compatibility and improved resistance to chemicals and low-temperature impact and is freed from the problem of the thickness dependence of impact strength, by blending a specified thermoplastic elastomer with a compsn. consistng of an arom. polycarbonate resin and an arom. satd. polyester resin.
CONSTITUTION: An elastomer compsn. obtd. by kneading at least 50wt% hydrogenated satd. block copolymer of the formula (wherein A, A' are each an arom. vinyl hydrocarbon block; B is a hydrogenated conjugated diene block) such as KRATON G (a product of Shell Chemical Co.), not more than 50wt% thermoplastic methacrylate copolymer (e.g. MBS resin) and butyl rubber (e.g. polyisobutylene) in the presence of 0.05W2wt% of an org. peroxide such as t-butyl peroxide with heating, is used. An arom. polycarbonate resin, an arom. satd. polyester resin and not more than 20wt% (based on the entire quantity of resin compsn.) said elastomer compsn. are blended together.
