[PROBLEMS] To provide a lubricating thermoplastic resin composition which is excellent in lubricity and surface appearance of a molded article, and maintains lubricity permanently. [MEANS FOR SOLVING PROBLEMS] As a copolymer of a monomer mixture containing an aromatic vinyl and vinyl cyanide, an acid-modified copolymer (A) having a carboxyl group in a molecular chain, a functional group (B1) capable of reacting with a carboxyl group, (B) having a functional group-containing lubricant (B2) in the same molecule. And may contain other thermoplastic resins (D) other than the graft copolymer (C) and / or the acid-modified copolymer (A). |
