Patent ID: 8450403

Claim:
A polycarbonate resin composition comprising: (A) about 78 to about 99.5 wt% of a polycarbonate resin; (B) 0.6 to about 20 wt% of a polymer including a reactive group that is reactive with a hydroxyl group, wherein the polymer including a reactive group is a copolymer of an aromatic vinyl compound and a vinyl cyanide compound comprising a substituent represented by the following Chemical Formula 2 at its side chain: wherein, in the above Chemical Formula 2, n ranges from 0 to 10, m is 0 or 1, wherein at least one CH 2 of (CH 2 ) n is optionally substituted with O, S, SO 2 , COO, CO, SiR′R″, or a combination thereof, wherein R′ and R″ are each independently hydrogen or substituted or unsubstituted C1 to C10 alkyl, and at least one H of (CH 2 ) n is optionally substituted with substituted or unsubstituted C1 to C10 alkyl, R is substituted or unsubstituted C6 to C30 arylene or substituted or unsubstituted C1 to C20 alkylene, and X is a reactive group comprising an epoxy group; and (C) about 0.0001 to about 2 wt% of an ionic compound comprising tetraphenylphosphonium benzoate, tetraphenylphosphonium acetate, tetraphenylphosphonium phenolate, tetraphenylphosphonium tetraphenylborate, tetra-n-butylphosphonium hydroxide, tetra-n-phenylphosphonium hydroxide, or a combination thereof, wherein the polymer including a reactive group and the ionic compound are included at a mixed weight ratio of about 1:1 to about 10:1.
