Document Type and Number:
WIPO Patent Application WO/2022/145727
Kind Code:
A1
Abstract:
A thermoplastic resin composition of the present invention comprises: about 100 parts by weight of a rubber-modified aromatic vinyl-based copolymer resin containing a diene-based rubber-modified vinyl-based graft copolymer, an acrylic rubber-modified vinyl-based graft copolymer, a large-particle diameter rubber copolymer having an average particle diameter of about 5 to about 10 μm, and an aromatic vinyl-based copolymer resin; about 5 to about 25 parts by weight of a polyetheresteramide block copolymer; about 0.05 to about 1.5 parts by weight of a silver (Ag)-based compound; and about 1 to about 15 parts by weight of zinc oxide, wherein the gloss degree of a 3.2-mm thick sample is about 40 to about 70%, as measured at an angle of 60° according to ASTM D523. The thermoplastic resin composition is excellent in low gloss, antiviral properties, weather resistance, impact resistance, and so on.
