Abstract:
A thermoplastic resin composition for a refrigerator according to the present invention can include (A) about 20 to about 40 parts by weight of an acrylonitrile-butadiene-styrene graft copolymer resin prepared by grafting in emulsion polymerization about 60 to about 30% by weight of a monomer mixture comprising a cyanide vinyl compound and an aromatic vinyl compound to about 40 to about 70% by weight of a rubber polymer having an average particle size of about 0.1 to about 0.4 μm; (B) about 1 to about 20 parts by weight of a styrenic copolymer comprising (b1) about 0 to about 75% by weight of a styrenic copolymer prepared by copolymerizing about 5 to about 20% by weight of a rubber polymer having an average particle size of about 0.1 to about 10 μm, about 10 to about 30% by weight of a cyanide vinyl compound, and about 65 to about 85% by weight of an aromatic vinyl compound, and (b2) about 25 to about 100% by weight of a styrenic copolymer prepared by copolymerizing about 5 to about 20% by weight of a rubber polymer having an average particle size of about 0.1 to about 10 μm and about 80 to about 95% by weight of an aromatic vinyl compound; and (C) about 50 to about 79 parts by weight of a cyanide vinyl-aromatic vinyl copolymer.
