[Object] To provide lubricating thermoplastic resin compositions that can give formed articles exhibiting excellent lubricating properties and surface appearance and maintaining the lubricating properties permanently.
[Solution] The lubricating thermoplastic resin composition includes an acid-modified copolymer (A) of a monomer mixture including an aromatic vinyl and a vinyl cyanide, the copolymer having a carboxyl group in the molecular chain, and a functionalized lubricant (B) having, in the molecule, a functional group (B1) capable of reacting with the carboxyl group and a lubricating segment (B2) having lubricating properties. The composition may further include a graft copolymer (C) and/or an additional thermoplastic resin (D) other than the acid-modified copolymer (A).
[目的]提供润滑性热塑性树脂组合物,该组合物可以使成形物品具有优异的润滑性能和表面外观,并能永久保持润滑性能。
[解决方案] 润滑热塑性树脂组合物包括一种酸改性共聚物(A),该共聚物的单体混合物包括芳香族乙烯基和乙烯基氰化物,共聚物的分子链中含有一个羧基,以及一种官能化润滑剂(B),该润滑剂的分子中含有一个能与羧基反应的官能团(B1)和一个具有润滑性能的润滑段(B2)。组合物还可进一步包括接枝共聚物 (C) 和/或除酸改性共聚物 (A) 之外的其他热塑性树脂 (D)。
