(57) [Summary] [Objective] To provide a flame-retardant styrene resin composition having excellent heat resistance, light resistance and impact resistance. [Structure] 100 parts by weight of a styrene resin, 1 to 24 parts by weight of a compound represented by the following general formula (1), and a molecular weight of 100 1 to 12 parts by weight of a bromine-containing epoxy polymer of 0 to 10000, tris (tribromoneopentyl) phosphate 1 To 15 parts by weight and 0 to 10 parts by weight of antimony trioxide, and the total amount of the compound represented by the general formula (1), the bromine-containing epoxy polymer, and tris (tribromoneopentyl) phosphate. Is 5 to 26 parts by weight. [Chemical 1] [R 1 represents -CH 3 or H. A is or -SO 2 those represented by the following formula (2) - indicates a. ] [Chemical 2] |
