PURPOSE:To obtain the title composition which can give a molding excellent in mechanical strengths, heat resistance and surface smoothness even at low mold temperature by mixing a mixture of a polyethylene terephthalate resin with a specified block copolymer with a glass fiber, a specified wollastonite and talc. CONSTITUTION:100pts.wt. mixture (A) comprising 20-90pts.wt. polyethylene terephthalate resin and 10-80pts.wt. block copolymer comprising 10-45wt.% polyether compound and 55-90wt.% polyethylene terephthalate resin and/or ethylene terephthalate resin oligomer is mixed with 10-35pts.wt. glass fiber (B), 4-11pts.wt. wollastonite (C) surface-treated with an aminosilane compound and/or an epoxysilane compound and 1-5pts.wt. talc (D). In this way, the title composition which can give a molding excellent in surface properties, mechanical strengths and heat resistance even at a mold temperature <=100 deg.C can be obtained. |
