Abstract
A thermoplastic resin composition of the present invention capable of improving the strength and surface gloss of a molded article is comprising 100 parts by weight of a thermoplastic resin (a) and 0.5 to 30 parts by weight of a core-shell polymer composition (b), wherein the core-shell polymer composition (b) is obtained by polymerizing a shell-constituting component in the presence of a core obtained by polymerizing a core-constituting component, the core-constituting component contains 70% to 99.95% by weight of an alkyl acrylate having an alkyl group of 2 to 18 carbon atoms, 0.05% to 10% by weight of a polyfunctional monomer, and 0% to 20% by weight of a monomer copolymerizable with the alkyl acrylate and/or the polyfunctional monomer, the total amount of which is 100% by weight, the polyfunctional monomer is one or more selected from the group consisting of polypropylene glycol diacrylate and polypropylene glycol dimethacrylate, and the molecular weight of a component soluble in methyl ethyl ketone and insoluble in methanol of the core-shell polymer composition (b) is 500,000 or higher.
