THERMOPLASTIC RESIN COMPOSITION, METHOD FOR MANUFACTURING SAME, AND METAL-PLATED MOLDED PRODUCT MANUFACTURED FROM SAME

The present invention relates to a thermoplastic resin composition, a method of preparing the thermoplastic resin composition, and a metal-plated molded article manufactured using the thermoplastic resin composition. More specifically, the thermoplastic resin composition of the present invention includes 100 parts by weight of a base resin including 5 to 40 % by weight of a vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound graft copolymer (a) containing conjugated diene rubber having a particle diameter of 0.05 ?m to 0.2 ?m, 5 to 40 % by weight of a vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound graft copolymer (b) containing conjugated diene rubber having a particle diameter of greater than 0.2 ?m and less than or equal to 0.5 ?m, and 50 to 80 % by weight of an aromatic vinyl compound-vinyl cyanide compound copolymer (c); and more than 0.01 parts by weight and less than 2 parts by weight of the compound represented by Formula 1 having a kinematic viscosity (25 ?C) greater than 5 cSt and less than 200 cSt. According to the present invention, when the thermoplastic resin composition of the present invention is plated, non-plating may be prevented even under conditions, such as reduced etching time, that promote the occurrence of a non-plating phenomenon. In addition, the thermoplastic resin composition of the present invention has mechanical properties equal or superior to those of conventional resins and excellent thermal properties and plating adhesion. Accordingly, after the thermoplastic resin composition is plated, the thermoplastic resin composition has an excellent appearance.
