PURPOSE:To provide the title resin composition of high crystallization rate, comprising a polyethylene terephthalate-based resin blend, metal salt of copolymer from alpha-olefin and alpha,beta-unsaturated carboxylic acid, and metal salt of organic carboxylic acid. CONSTITUTION:The objective composition comprising (A) 100 pts.wt. of a resin blend comprising A1: <=95 pts.wt. of a polyethylene terephthalate resin and A2: >=5 pts.wt. of a block copolymer containing 50-97wt.% of ethylene terephthalate segment and 3-50wt.% of polyether segment, (B) 0.5-50 pts.wt. of a copolymer from alpha-olefin and alpha,beta-unsaturated carboxylic acid with 5-95mol% of the COOH group in the form of metal salt (pref. Na salt of a copolymer from ethylene and methacrylic acid), (C) 0.05-5 pts.wt. of at least one kind of compound selected from respective metal salts of p-t-butyl benzoic acid, montanic acid and palmitic acid, and (D) 0-150 pts.wt. of a fibrous reinforcing material. |
