US 11,634,575 B2 · Thermoplastic resin composition, method of preparing the same, and molded article including the same

Abstract

The present invention relates to a thermoplastic resin composition, a method of preparing the same, and a molded article including the same. More specifically, the present invention relates to a thermoplastic resin composition including 100 parts by weight of a base resin including a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound graft copolymer and an α-methyl styrene compound-vinyl cyanide compound copolymer and 0.4 to 3 parts by weight of an alkoxylated polyethyleneimine, a method of preparing the thermoplastic resin composition, and a molded article including the thermoplastic resin composition. The thermoplastic resin composition according to the present invention has improved chemical resistance to solvents such as thinner without degradation in fluidity and mechanical properties, and thus has excellent paintability.
