Abstract

The thermoplastic resin composition of the present invention comprises: (A) a rubber-modified aromatic vinyl-based graft copolymer resin; (B) a polyester resin; (C) a maleimide-based polymer; (D) a copolymer resin of a modified aromatic vinyl compound-cyanide vinyl compound comprising a functional group which can react with a polyester; and (E) an aromatic vinyl-based resin copolymerized with an alkyl(meth)acrylate, wherein the aromatic vinyl-based resin copolymerized with the alkyl(meth)acrylate (E) is included in the composition at approximately 6 to 12 percent by weight.

Claims

1. A molded product comprising a thermoplastic resin composition comprising:

(A) about 10 wt % to about 60 wt % of a rubber-modified aromatic vinyl graft copolymer resin;

(B) about 10 wt % to about 60 wt % of a polyester resin;

(C) about 1 wt % to about 40 wt % of a maleimide-based polymer, wherein the maleimide-based copolymer (C) is a copolymer of an N-substituted maleimide, an unsaturated dicarboxylic acid anhydride, and a vinyl monomer;

(D) about 5 wt % to about 40 wt % of a modified aromatic vinyl compound-vinyl cyanide compound copolymer resin containing a functional group capable of reacting with polyester,

wherein the modified aromatic vinyl compound-vinyl cyanide compound copolymer resin (D) has a weight average molecular weight from about 50,000 g/mol to about 200,000 g/mol and

wherein the modified aromatic vinyl compound-vinyl cyanide compound copolymer resin (D) is a copolymer of about 0.01 mol % to about 5 mol % of (d1) an unsaturated compound represented by the following Formula 1 and (d2) about 95 mol % to about 99.99 mol % of a vinyl-based compound,

2. The molded product comprising the thermoplastic resin composition according to claim 1, wherein the polyester resin (B) is a recycled polyester resin.

3. The molded product comprising the thermoplastic resin composition according to claim 1, wherein the maleimide-based polymer (C) has a weight average molecular weight from about 80,000 g/mol to about 200,000 g/mol.

4. The molded product comprising the thermoplastic resin composition according to claim 1, wherein the maleimide-based polymer (C) comprises about 20 mol % to about 55 mol % of repeat units derived from maleimide.

5. The molded product comprising the thermoplastic resin composition according to claim 1, wherein the (E) aromatic vinyl resin copolymerized with an alkyl(meth)acrylate has a weight average molecular weight from about 80,000 g/mol to about 200,000 g/mol.

6. The molded product comprising the thermoplastic resin according to claim 1, wherein the molded product has a metal layer formed on a surface thereof.

7. The molded product comprising the thermoplastic resin composition according to claim 1, wherein the (E) aromatic vinyl resin is a copolymer consisting of an alkyl(meth)acrylate, aromatic vinyl compound, and vinyl cyanide.
