PROBLEM TO BE SOLVED: To obtain the subject composition, having a high strength and rigidity, excellent in sliding properties and having a good appearance by compounding a mixture of an aromatic polycarbonate resin with a reinforcing material and a sliding property imparting agent with a specific polyester elastomer. SOLUTION: This composition is obtained by compounding (A) 95-40 wt.% thermoplastic resin composed of (i) 60-100 wt.% aromatic polycarbonate resin and (ii) 40-0 wt.% thermoplastic resin such as a thermoplastic graft copolymer prepared by grafting an aromatic vinyl compound and a vinyl cyanide compound onto a diene rubber component or a polyester resin with (B) 3-55 wt.% reinforcing material, (C) 0.1-10 wt.% sliding property imparting agent and (D) 1-20 wt.% polyester elastomer containing a poly(oxyalkylene) glycol component. The resultant composition has >=30,000 kgf/cm<2> flexural modulus and <=1.50 mm major axis of a cross section formed in a pin-shaped test specimen by abrasion. |
