Abstract
A thermoplastic resin composition comprising: (A) 40 to 99.8 parts by weight of a rubber-modified styrene base thermoplastic resin, (B) 0.1 to 20 parts by weight of a copolymer having an epoxy group but comprising no olefin, and (C) 0.1 to 50 parts by weight of a polymer having at least one functional group selected from the group consisting of a carboxyl group, an acid anhydride group, a hydroxyl group and a nitrogen-containing base group with the total amount of the rubber-modified styrene base thermoplastic resin (A), the copolymer (B) and the polymer (C) being 100 parts by weight and the content of the rubber in the composition being from 5 to 40 % by weight based on the weight of the composition, which has good flowability and imparts a uniformly delustered surface and good impact resistance to a molded article.
