PURPOSE:To obtain the titled composition outstanding in flame-retardancy, heat resistance, etc., without impairing mechanical properties, and suitable for exterior members used in light electrical appliances and office machines, by incorporating a rubber-modified styrene resin or its blend with styrene resin in specified amount of specific bromine-based compound, etc. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts.wt. of a rubber-modified styrene resin or its blend with a styrene resin with a heat distortion temperature >=75 deg.C with (B) 1-45(pref., 2-30)pts.wt. of a bromine-based compound with a bromine content >=40wt.% and melting point >=80 deg.C (e.g., decabromodiphenyl oxide), (C) 0.5-15pts.wt. of antimony trioxide, and (D) 1-30(pref. 5-25)pts.wt. of glass fiber having a diameter 1-20mu and fiber length 0.3-10mm. The molded articles made from this composition have a heat distortion temperature >=85 deg.C and impact strength >=5kg.cm/cm.
