Abstract
(EN)
The present invention pertains to a thermoplastic resin composition comprising: a graft copolymer containing a C4-10 alkyl (meth)acrylate-based monomer unit, a styrene-based monomer unit, and a vinyl cyan-based monomer unit; a first styrene-based copolymer containing a C1-3 alkyl-substituted styrene-based monomer unit and a vinyl cyan-based monomer unit; and a second styrene-based copolymer containing a non-substituted styrene-based monomer unit and a vinyl cyan-based monomer unit, the thermoplastic resin composition having remarkably excellent heat resistance, chemical resistance, and appearance characteristics while retaining the basic physical properties thereof.
