Abstract
The present disclosure relates to a thermoplastic resin composition including a styrene-based copolymer comprising a (meth)acrylate-based monomer, an aromatic vinyl-based monomer, and a maleimide-based monomer; a first graft copolymer including an acrylic-based rubber polymer, an aromatic vinyl-based monomer, and a vinyl cyanide-based monomer; and a second graft copolymer comprising an acrylic-based rubber polymer, an aromatic vinyl-based monomer, and a vinyl cyanide-based monomer, wherein the styrene-based copolymer has a residual oligomer content of 0.37% by weight or less, and the acrylic-based rubber polymer of the first graft copolymer and the acrylic-based rubber polymer of the second graft copolymer have different average particle diameters. A method of preparing the thermoplastic resin composition, and a molded article including the thermoplastic resin composition are also disclosed.
