ECO-FRIENDLY TRANSPARENT THERMOPLASTIC RESIN COMPOSITION, AND MOLDED PRODUCT FORMED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2024/128653
Kind Code:
A1
Abstract:
A thermoplastic resin composition of the present invention comprises: approximately 100 parts by weight of a rubber-modified aromatic vinyl-based copolymer resin, which comprises approximately 15-35 wt% of a rubber-modified vinyl-based graft copolymer obtained by grafting, onto a rubbery polymer, an alkyl (meth)acrylate, an aromatic vinyl-based monomer and a vinyl cyanide monomer, and approximately 65-85 wt% of an aromatic vinyl-based copolymer resin obtained by polymerizing an alkyl (meth)acrylate, an aromatic vinyl-based monomer and a vinyl cyanide monomer; and approximately 1-13 parts by weight of a polyalkyl (meth)acrylate resin, wherein the alkyl (meth)acrylate in the aromatic vinyl-based copolymer resin comprises approximately 30 wt% or more of a recycled material on the basis of the total 100 wt% thereof, the haze of a specimen having a thickness of 1 mm, measured according to ASTM D1003, is approximately 3.5% or less, and light transmittance is approximately 85% or more. The thermoplastic resin composition has excellent eco-friendliness, transparency, impact resistance and rigidity, balance of physical properties thereof and the like.
