Title:
THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE FORMED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2021/221292
Kind Code:
A1
Abstract:
A thermoplastic resin composition according to the present invention is a thermoplastic resin composition comprising: about 100 parts by weight of a rubber-modified aromatic vinyl-based copolymer resin comprising about 18 to 28 weight% of a rubber-modified vinyl-based graft copolymer and about 72 to 82 weight% of an aromatic vinyl-cyanide vinyl-based copolymer resin; about 0.1 to 1 part by weight of zeolite; and about 0.05 to 0.6 parts by weight of an alkyl phosphate of 10 to 20 carbon atoms, wherein the thermoplastic resin composition is characterized in that a residual amount of the vinyl cyanide compound in 2 g of a thermoplastic resin composition specimen in a pellet form is about 10 ppm or less as measured at 250℃ by a headspace gas chromatograph mass spectrometer. The thermoplastic resin composition is excellent in impact resistance, rigidity, etc., and can reduce the residual amount of the vinyl cyanide compound.
