WIPO Patent Application WO/2022/092755

Kind Code:

A1

Abstract:

The present invention relates to a thermoplastic resin composition, a method for manufacturing same, and a molded article comprising same. More specifically, provided is a thermoplastic resin composition comprising a base resin and polysiloxane in a predetermined composition ratio, the base resin comprising a vinyl cyan compound-conjugated diene rubber-aromatic vinyl compound graft copolymer, an alkyl acrylate rubber-vinyl cyan compound-aromatic vinyl compound graft copolymer, and an aromatic vinyl compound-vinyl cyan compound copolymer, wherein the alkyl acrylate rubber-vinyl cyan compound-aromatic vinyl compound graft copolymer has a graft rate of 42% or more and is included in an amount of 0.1 to 10% by weight with respect to 100% by weight of the total base resin. The thermoplastic resin composition not only has excellent colorability, but also exhibits a low clutch force, and at the same time has excellent dimensional stability against heat aging, thereby having an excellent clutch force retention rate.
