PURPOSE:To improve moldability in a low-temperature mold and to increase impact resistance in a low-temperature regin, by blending an inorg. nucleating agent, a modified polyolefin, a copolyolefin and an ester plasticizer with polyethylene terephthalate contg. an arom. polycarbonate added thereto. CONSTITUTION:0.05-10pts.wt. at least one member (a) selected from among inorg. nucleating agents having an average particle size of 50mu or below and high-molecular compds. or org. compds. contg. carboxyl groups in the form of a metal salt, 3-30pts.wt. modified polyolefin (b) obtd. by adding 0.001-10mol% of at least one compd. selected from alicyclic carboxylic acids contg. a cis double bond in its ring and functional derivatives thereof to a polyolefin, 1-30pts.wt. copolymer (c) composed of 80-99wt% alpha-olefin, 1-20wt% glycidyl (meth)acrylate and 0-19wt% vinyl acetate, 0.3-10pts.wt. ester plasticizer (d) and 0-150pts.wt. reinforcing fiber (e) are blended with a component (f) composed of 60-90pts.wt. polyester and 10-40pts.wt. arom. polycarbonate. |
