Provided is a thermoplastic resin composition which includes: a first copolymer including an acrylic graft copolymer; a second copolymer including an alkyl-substituted styrene-based monomer unit, a vinyl cyanide-based monomer unit, and a (meth)acrylate-based monomer unit; and a third copolymer including an alkyl-unsubstituted styrene-based monomer unit, a vinyl cyanide-based monomer unit, and a (meth)acrylate-based monomer unit. According to the present invention, a thermoplastic resin composition and a thermoplastic resin molded article, which are excellent in heat resistance, colorability, and scratch resistance, can be provided.

Thermoplastic resin composition and thermoplastic resin molded article

Provided is a thermoplastic resin composition which includes: a first graft copolymer including a Cto Calkyl (meth)acrylate-based monomer unit, an aromatic vinyl-based monomer unit, and a vinyl cyan-based monomer unit; a second graft copolymer including a Cto Calkyl (meth)acrylate-based monomer unit, an aromatic vinyl-based monomer unit, and a vinyl cyan-based monomer unit; and a first styrene-based copolymer being a copolymer of a monomer mixture including a Cto Calkyl-substituted styrene-based monomer, a vinyl cyan-based monomer, and a Cto Calkyl (meth)acrylate-based monomer, wherein the first graft copolymer and the second graft copolymer have cores having mutually different average particle diameters. The thermoplastic resin composition is excellent in colorability, weather resistance, tensile strength, flexural strength, and impact strength.
