Abstract

The present invention provides a thermoplastic resin and a molded article using the same, wherein the thermoplastic resin comprises: (A) 10 parts by weight to less than 30 parts by weight of a butadiene-based graft copolymer; (B) 5 parts by weight or more to less than 30 parts by weight of an acrylate-based graft copolymer; (C) 35 parts by weight to 65 parts by weight of a vinyl cyanide-aromatic vinyl-based copolymer; (D) 1 part by weight to 10 parts by weight of an ethylene-alkyl acrylate-based copolymer elastomer based on the total 100 parts by weight of (A), (B), and (C); and (E) 1 part by weight to 10 parts by weight of a polyester-based elastomer.

Dependent claims

A resin composition comprising:

(A) 10 parts by weight to less than 30 parts by weight of a butadiene-based graft copolymer including 30 wt % to 70 wt % of a butadiene-based rubber polymer core, and 30 wt % to 70 wt % of a graft shell having a vinyl cyanide monomer-derived unit and an aromatic vinyl monomer-derived unit;
(B) 5 parts by weight or more to less than 30 parts by weight of an acrylate-based graft copolymer including 30 wt % to 70 wt % of an acrylate-based rubber polymer core, and 30 wt % to 70 wt % of a graft shell having a vinyl cyanide monomer-derived unit and an aromatic vinyl monomer-derived unit;
(C) 35 parts by weight to 65 parts by weight of a vinyl cyanide-aromatic vinyl-based copolymer;
(D) 1 part by weight to 10 parts by weight of an ethylene-alkyl acrylate-based copolymer elastomer based on the total 100 parts by weight of (A), (B), and (C);
and
(E) 1 part by weight to 10 parts by weight of a polyester-based elastomer.
