Abstract
A thermoplastic resin composition includes: a first rubber-modified vinyl graft copolymer obtained by grafting a monomer mixture including an aromatic vinyl monomer and a vinyl cyanide monomer to a diene rubber polymer; a second rubber-modified vinyl graft copolymer obtained by grafting a monomer mixture including an aromatic vinyl monomer and a vinyl cyanide monomer to an acrylate rubber polymer; a first aromatic vinyl-vinyl cyanide copolymer having a weight average molecular weight of about 250,000 g/mol to about 450,000 g/mol and including about 25 wt % to about 31 wt % of a repeat unit derived from a vinyl cyanide monomer; a second aromatic vinyl-vinyl cyanide copolymer having a weight average molecular weight of about 70,000 g/mol to about 150,000 g/mol and including about 33 wt % to about 42 wt % of a repeat unit derived from a vinyl cyanide monomer; and a third aromatic vinyl-vinyl cyanide copolymer having a weight average molecular weight of about 70,000 g/mol to about 150,000 g/mol and including about 25 wt % to about 31 wt % of a repeat unit derived from a vinyl cyanide monomer. The thermoplastic resin composition can have excellent properties in terms of chemical resista…
