PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition not causing surface delamination in resin molded products comprising a polycarbonate resin and a styrene- based resin, improved in impact resistance and esp. surface impact strength near to practical use, physical properties, excellent in moldability, impact resistance and aging resistance even when aflame retardant is blended and capable of being recycled. SOLUTION: This thermoplastic resin composition includes 100 pts.wt. resin consisting of (A) 20-98 wt.% polycarbonate resin and (B) 80-2 wt.% styrene-based resin, (C) 0.1-20 pts.wt. block copolymer having a polymer block comprising an aromatic vinyl compound as a principal component and a polymer block comprising a conjugated diene compound as a principal component or epoxy- modified block copolymer where double bonds of partially hydrogenated product from the above block copolymer are epoxidized, and (D) 0.5-20 pts.wt. core-shell- type graft rubber-like elastomer. |
