PURPOSE:To provide the subject resin composition having an excellent mold release characteristics and a ready crystallizability, low in generation of decomposed volatile gases during molding and excellent in thermal stability and mechanical strength. CONSTITUTION:With a composition composed of (A) 20-80wt.% polyethylene terephthalate, (B) 0-60wt.% inorganic filler, (C) 1-12wt.% sodium salt of an ionic copolymer, e.g. a sodium salt of an ethylene-acrylic acid copolymer, (E) 2-25wt.% brominated flame-retardant and (F) 1-10wt.% sodium antimonate, (D) 1-10wt.% polyethylene glycol having both the end groups blocked (>=80% ratio of both end groups blocked with methyl group and 700-5000 weight-average molecular weight) as a plasticizer or a crystallization promoter is blended. |
