PURPOSE: Provided is a flame resistant thermoplastic resin composition, which has excellent stability against fire and flame resistance, and is environmental-friendly due to the absence of halogen-containing flame retardant compounds. CONSTITUTION: The flame resistant thermoplastic resin composition comprises: (A) 100 parts by weight of a rubber-modified styrene-based resin composed of (a1) 20-100 wt% of a graft copolymer resin obtained by graft polymerization of 5-65 wt% of a rubbery polymer, 30-95 wt% of an aromatic vinyl monomer, 0-20 wt% of a monomer which can be copolymerized with the aromatic vinyl monomer and 0-15 wt% of a monomer for supplementing processability and heat resistance, and (a2) 0-80 wt% of a copolymer resin obtained by copolymerization of 60-90 wt% of an aromatic vinyl monomer, 10-40 wt% of a monomer which can be copolymerized with the aromatic vinyl monomer and 0-30 wt% of a monomer for supplementing processability and heat resistance; and (B) 15-40 parts by weight of a cyclic alkyl phosphonic acid compound. |
