PROBLEM TO BE SOLVED: To modify a polymer blend consisting essentially of a polycarbonate based resin and a rubber-modified polystyrene-based resin into a thermoplastic resin composition having the fluidity and impact strength comparable to those of a polycarbonate-based resin containing an ABS-based resin blended therein and to obtain a nontoxic flame retarded thermoplastic resin based on the modified composition. SOLUTION: This thermoplastic resin composition comprises 0.1-5 pts.wt. polyphenylene ethereal resin in 100 pts.wt. resin composition composed of 30-95 wt.% polycarbonate-based resin and 5-70 wt.% rubber-modified polystyrene-based resin. Furthermore, the flame retarded thermoplastic resin composition is obtained by adding 1-40 pts.wt. organophosphorus compound and 0.05-5 pts.wt. fluoroethylene-based polymer to the thermoplastic resin composition. |
