|Title:||FLAME RETARDANT THERMOPLASTIC RESIN COMPOSITION HAVING EXCELLENT THERMAL STABILITY, PREPARATION METHOD THEREFOR, AND MOLDED PRODUCT PREPARED THEREFROM|
Provided is a flame retardant thermoplastic resin composition comprising: (A) 100 parts by weight of a base resin comprising 10-90 wt% of a vinyl cyano compound-conjugated diene compound-aromatic vinyl compound copolymer grafted with a reactive emulsifier, and 10-90 wt% of an aromatic vinyl compound-vinyl cyano compound copolymer; (B) 1-30 parts by weight of a bromine-based flame retardant; (C) 0.5-8 parts by weight of an antimony-based compound; and (D) 0.1-5 parts by weight of a polyol compound. The flame retardant thermoplastic resin composition of the present invention and a molded product prepared therefrom have excellent thermal stability and flame retardancy, thereby having an advantage of not generating harmful gas even during high-temperature, high-pressure, and high-speed injection.
