PURPOSE:A composition providing a molded article having high crystallization rate, showing improved releasability even at low temperature, having improved impact strength, obtained by blending PET with a nucleating agent, a modified polyolefin, a specific copolymer and a specified ester plasticizer. CONSTITUTION:100pts.wt. PET is blended with 0.05-10pts.wt. one or more of an inorganic crystal nucleating agent having <=50 average particle diameter, an organic compound containing a metallic salt of carboxyl group, and a high polymer compound containing a metallic salt of carboxyl group, 3-30pts.wt. modified polyolefin or modified olefinic elastomer obtained by adding 0.01-10mol% alicyclic carboxylic acid containing cis type double bond in the ring to a polyolefin or olefinic elastomer, 1-30pts.wt. copolymer consisting of 80-99wt.% alpha-olefin and 1-20wt.% glycidyl methacrylate or glycidyl acrylate, 0.3-10pts.wt. ester plasticizer shown by the formula I-formula III (R1 is alkylene; R2, R9, and R11 are alkyl, etc.; R10 is phenyl, etc.; X is alkylene, etc.; m and n are >=1), and 0-150pts.wt. fibrous reinforcing material. |
