Abstract
The present invention relates to a thermoplastic resin composition including a diene-based graft polymer; a first polymer including a vinyl cyanide-based monomer and an alkyl-substituted styrene-based monomer; a second polymer including a vinyl cyanide-based monomer, an aromatic vinyl-based monomer, and a (meth)acrylate-based monomer; a third polymer including a vinyl cyanide-based monomer and an alkyl-unsubstituted styrene-based monomer and having a weight-average molecular weight of 80,000 to 220,000 g/mol; a fourth polymer including a vinyl cyanide-based monomer and an alkyl-unsubstituted styrene-based monomer and having a weight-average molecular weight of 1,500,000 to 5,000,000 g/mol; and a fifth polymer including an olefin-based monomer and having a density of 970 to 1,000 kg/mmeasured in accordance with ASTM D1505, wherein the fifth polymer is included in 0.10 to 3.00 parts by weight with respect to 100 parts of the diene-based graft polymer, the first polymer, the second polymer, the third polymer, and the fourth polymer.
