摘要： A flame-retardant rubber-modified styrene resin composition comprising, as essential components, (A) a rubber-modified styrene resin, (B) a halogenated bisphenol type polycarbonate oligomer, (C) a halogenated bisphenol type compound, and (D) a halogenated polyolefin compound. The resin composition contains these components (A), (B), (C), and (D) at specific proportions, and its contents of the components (B) and (C) must be at a specified ratio. The resin composition is not only flame-retardant but also possesses such excellent characteristics as a high degree of light resistance, heat resistance, impact resistance and fluidity when it is molded. It can be molded into articles of various shapes and has a wide variety of applications in business machines, electric appliances, and automobile parts.

摘要： A flame-retardant styrene resin composition comprising 100 parts by weight of a styrene resin, 1 to 25 parts by weight of at least one flame retarder (A) represented by the formula (I): ##STR1## wherein X is Br or Cl; and each of h and i is an integer of 2 to 5, and 1 to 25 parts by weight of at least one flame retarder (B) represented by the formula (II): ##STR2## wherein X is Br or Cl; each of l and m is an integer of 1 to 4; n means that the number of repeating units is 1 to 50; each of R.sup.1 and R.sup.2 is a C.sub.1-12 alkyl group; and each of R.sup.3 and R.sup.4 is a hydrogen atom, a lower alkyl group, an alkylphenyl group or a phenyl group, the total amount of (A) and (B) being 2 to 40 parts by weight. This composition has excellent heat resistance and excellent heat stability in addition to flame retardancy.
