Patent ID: 11286383

Abstract:
Provided is a thermoplastic resin composition which includes: a first graft copolymer including a C4 to C10 alkyl (meth)acrylate-based monomer unit, a C1 to C3 alkyl-substituted styrene-based monomer unit, and a vinyl cyan-based monomer unit; a second graft copolymer including a C4 to C10 alkyl (meth)acrylate-based monomer unit, an alkyl-unsubstituted styrene-based monomer unit, and a vinyl cyan-based monomer unit; a first styrene-based copolymer including a C1 to C3 alkyl-substituted styrene-based monomer unit and a vinyl cyan-based monomer unit; a second styrene-based copolymer including an alkyl-unsubstituted styrene-based monomer unit and a vinyl cyan-based monomer unit; and an olefin-based copolymer including a C1 to C3 alkyl (meth)acrylate-based monomer unit. The thermoplastic resin composition exhibits remarkably excellent chemical resistance and remarkably excellent appearance characteristics while maintaining basic properties.
