PURPOSE:To obtain the above composition having excellent color-developing property, thermal stability and flame-retardancy, by using antimony pentoxide in combination with a flame retardant composed of octabromodiphenyl oxide and/or a brominated epoxy oligomer having a specific molecular weight. CONSTITUTION:The objective composition is produced by compounding (A) 100pts.wt. of a thermoplastic resin composition composed of (A1) 20-100wt.% of a rubber-reinforced styrene resin and (A2) 0-80wt.% of other thermoplastic resin with (B) 5-25pts.wt., preferably 7-200pts.wt. of octabromodiphenyl oxide and/or a brominated epoxy oligomer having a molecular weight of <=5,000, (C) 1-10pts.wt. of antimony pentoxide and (D) 0-3pts.wt. of a heat-stabilizing agent (e.g. dibutyltin maleate). |
