Claim Text:
1. A thermoplastic resin composition comprising: a polycarbonate resin; and a rubber-reinforced vinyl copolymer, wherein the rubber-reinforced vinyl copolymer comprises a matrix including a branched vinyl copolymer which is a polymer of a monomer mixture including an aromatic vinyl compound, a vinyl cyanide compound, an alkyl (meth)acrylate and a reactive monomer, and a dispersed rubbery polymer in the matrix, wherein the rubber-reinforced vinyl copolymer is obtained by dispersing about 1 wt % to about 20 wt % of the rubbery polymer in the matrix including the branched vinyl copolymer obtained by copolymerization of the monomer mixture, the monomer mixture comprising about 40 wt % to about 90 wt % of the aromatic vinyl compound, about 5 wt % to about 50 wt % of the vinyl cyanide compound, about 1 wt % to about 20 wt % of the alkyl (meth)acrylate, and about 0.1 wt % to about 10 wt % of the reactive monomer, based on 100 wt % of the rubber-reinforced vinyl copolymer.
