FIELD: polymer materials. SUBSTANCE: light-stabilized fire-resistant composition contains styrene homopolymer or copolymer of styrene with alpha-methylstyrene or p-methylstyrene, bromine-containing combustion inhibitor, UF emission absorber, space-hindered amine, and epoxidated fatty acid. The latter, when added to UF emission absorber, and space-hindered amine, when added to abovenamed copolymer, produce synergic effect with respect to stabilization of light. EFFECT: reduced decoloration of finished polymer upon irradiation. 12 cl, 2 tbl, 3 ex
