Disclosed is a thermoplastic resin composition, a method of preparing the same, and a molded article including the same. Also disclosed is a thermoplastic resin composition prepared by adding a recycled vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound copolymer and a recycled polycarbonate resin to a composition including a vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound graft copolymer, an α-methyl styrene-vinyl cyanide compound-aromatic vinyl compound copolymer, and an aromatic vinyl compound-vinyl cyanide compound copolymer according to a predetermined composition ratio.
A thermoplastic resin composition, comprising:
A method of preparing a thermoplastic resin composition, comprising kneading and extruding 10 to 40% by weight of a vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound graft copolymer (A), 10 to 40% by weight of an α-methyl styrene-vinyl cyanide compound-aromatic vinyl compound copolymer (B), 5 to 30% by weight of an aromatic vinyl compound-vinyl cyanide compound copolymer (C), 10 to 30% by weight of a recycled vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound copolymer (D), and 25 to 50% by weight of a recycled polycarbonate resin (E) at 200 to 280° C.,
