Abstract

Disclosed is a resin composition including (A) a polycarbonate resin and (B) a rubber modified vinyl-based graft copolymer, and (C) about 1 to about 9 parts by weight of a random copolymer of a compound represented by the following Chemical Formula 1, an aromatic vinyl monomer, and a vinyl cyanide monomer, based on about 100 parts by weight of the polycarbonate resin (A) and the rubber-modified vinyl-based graft copolymer (B):

wherein, in the above chemical formula, m is an integer ranging from 0 to 10, and X is phenyl, methylphenyl, methylethylphenyl, methoxyphenyl, cyclohexylphenyl, chlorophenyl, bromophenyl, phenylphenyl group, or benzylphenyl.

First claim

What is claimed is:

1. A resin composition, comprising
(A) a polycarbonate resin; (B) a rubber-modified vinyl-based graft copolymer; and (C) about 1 to about 9 parts by weight of a random copolymer of a compound represented by the following Chemical Formula 1, an aromatic vinyl monomer, and a vinyl cyanide monomer, based on about 100 parts by weight of the polycarbonate resin (A) and the rubber-modified vinyl-based graft copolymer (B):

wherein m is an integer ranging from 0 to 10, and X is phenyl, methylphenyl, methylethylphenyl, methoxyphenyl, cyclohexylphenyl, chlorophenyl, bromophenyl, phenylphenyl, or benzylphenyl,
wherein the (C) random copolymer is prepared by copolymerizing about 50 to about 90 wt % of a compound represented by Chemical Formula 1, about 9 to about 40 wt % of an aromatic vinyl monomer, and about 1 to about 10 wt % a vinyl cyanide monomer, and
wherein the resin composition further comprises a methylmethacrylate-butadiene-styrene (MBS) graft copolymer in an amount of about 1 to about 10 parts by weight based on about 100 parts by weight of the polycarbonate resin (A) and the rubber-modified vinyl-based graft copolymer (B).

2. The resin composition of claim 1 , comprising about 10 to about 90 parts by weight of the polycarbonate resin (A) and about 10 to about 90 parts by weight of the rubber modified vinyl-based graft copolymer (B), each based on about 100 parts by weight of the polycarbonate resin (A) and the rubber-modified vinyl-based graft copolymer (B).

3. The resin composition of claim 1 , wherein the rubber-modified vinyl-based graft copolymer (B) comprises about 5 to about 95 wt % of a mixture of an aromatic vinyl monomer and a vinyl cyanide monomer which is grafted on about 5 to about 95 wt % of a rubbery polymer comprising a butadiene rubber, a styrene/butadiene rubber, an acrylonitrile/butadiene rubber, an isoprene rubber, an ethylene/propylene rubber, an ethylene-propylene-diene terpolymer (EPDM) rubber, a polyorganosiloxane/polyalkyl(meth)acrylate rubber, or a combination thereof.

4. The resin composition of claim 1 , wherein the compound represented by the above Chemical Formula 1 comprises benzyl methacrylate, phenyl methacrylate, 2-phenylethyl methacrylate, 3-phenylpropyl methacrylate, 4-phenylbutyl methacrylate, or a combination thereof.

5. An article manufactured from the resin composition of claim 1 .

6. The resin composition of claim 1 , wherein the amount of the (C) random copolymer is about 1 to about 7 parts by weight based on about 100 parts by weight of the polycarbonate resin (A) and the rubber-modified vinyl-based graft copolymer (B).
