Abstract
(EN)
The present invention relates to a thermoplastic resin composition, comprising: a first graft polymer comprising a C4-C10 alkyl (meth)acrylate-based monomer unit, an aromatic vinyl-based monomer unit, and a vinyl cyan-based monomer unit; a second graft copolymer comprising a C4-C10 alkyl (meth)acrylate-based monomer unit, an aromatic vinyl-based monomer unit, and a vinyl cyan-based monomer unit; and a first styrene-based copolymer which is a copolymer of a monomer mixture comprising a C1-C3 alkyl-substituted styrene-based monomer, a vinyl cyan-based monomer, and a C1-C3 alkyl (meth)acrylate-based monomer, wherein the first graft copolymer and the second graft copolymer are different in terms of average core diameter. The thermoplastic resin composition has excellent colorability, weather resistance, tensile strength, flexural strength, and impact strength.
