PURPOSE: A thermoplastic resin composition is provided, which is improved in the weather resistance and the fluidity by employing 2,4,6-tri(2,4,6-tribromophenoxy)-1,3,5-triazine and decabromodiphenylethane. CONSTITUTION: The thermoplastic resin composition comprises 100 parts by weight of a rubber reinforced polystyrene resin which is prepared by polymerizing rubber, an aromatic monoalkenyl monomer and/or an alkyl ester monomer; 5-20 parts by weight of 2,4,6-tri(2,4,6-tribromophenoxy)-1,3,5-triazine represented by the formula 1; 5-20 parts by weight of decabromodiphenylethane; and 1-20 parts by weight of an auxiliary flame retardant. Preferably the ratio of 2,4,6-tri(2,4,6-tribromophenoxy)-1,3,5-triazine to decabromodiphenylethane is 1.5:1 to 1:1.5 by weight. |
