Thermoplastic resin composition having excellent colorability and mechanical and physical properties

摘要

Provided is a thermoplastic resin composition including: an acrylic graft copolymer (A), an aromatic vinyl-vinyl cyanide compound copolymer (B), a polyalkyl(meth)acrylate resin (C), and an acrylic compound-grafted silicon-based impact reinforcing agent (D). The thermoplastic resin composition can have excellent impact resistance and colorability with minimal or no deterioration of dimensional stability, molding processability, weather resistance and mechanical and physical properties.

主权项

1. A thermoplastic resin composition having impact resistance and colorability comprising:
a base resin comprising about 25 to about 50 wt % of a (meth)acrylic graft copolymer (A); about 55 to about 70 wt % of an aromatic vinyl-vinyl cyanide compound copolymer (B); about 0.1 to about 5 wt % of a polyalkyl(meth)acrylate resin (C); and optionally a (meth)acrylic acid alkyl ester component-containing styrene-based copolymer resin (E) wherein said percentages are based on (A), (B), (C), and when present (E); and about 0.1 to about 3 parts by weight of a (meth)acrylic compound-grafted silicon-based impact reinforcing agent (D) based on about 100 parts by weight of the base resin of (A), (B), (C) and (E) when present, wherein the (meth)acrylic graft copolymer (A) has a core-shell structure in which an unsaturated monomer including (meth)acrylate is grafted to a core including an acrylate-based rubber-like polymer to thereby form a shell.
