Abstract
Disclosed are a polyester/polycarbonate alloy resin composition that includes: (A) a mixed resin including (A-1) a polycarbonate resin having a weight average molecular weight ranging from about 30,000 to about 200,000 g/mol and (A-2) a polyester resin having an intrinsic viscosity of about 0.85 to about 1.52 dl/g; (B) an acryl-based resin; and (C) an impact-reinforcing agent, and a molded product made using the polyester/polycarbonate alloy resin composition.
Claims10
A polyester/polycarbonate alloy resin composition comprising:
- (A) about 100 parts by weight of a mixed resin including (A-1) about 10 to about 60 wt % of a polycarbonate resin having a weight average molecular weight ranging from about 30,000 to about 200,000 g/mol, and (A-2) about 40 to about 90 wt % of a polyester resin having an intrinsic viscosity of about 0.85 to about 1.52 dl/g;
- (B) about 0.1 to about 10 parts by weight of an acryl-based resin, wherein the acryl-based resin (B) is a terpolymer comprising an alkyl ester (meth)acrylate monomer, an ester (meth)acrylate monomer, or a combination thereof;
- an aromatic vinyl monomer comprising styrene, o-ethyl styrene, m-ethyl styrene, p-ethyl styrene, alpha methyl styrene or a combination thereof;
- and an unsaturated nitrile monomer comprising acrylonitrile, methacrylonitrile, ethacrylonitrile, or a combination thereof;
- and
- (C) about 1 to about 30 parts by weight of an impact-reinforcing agent.
