Title:
THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/101326
Kind Code:
A1
Abstract:
The present invention relates to a thermoplastic resin composition and, specifically, to a thermoplastic resin composition capable of implementing high gloss, high hardness, high weather resistance and low efflorescence characteristics, the thermoplastic resin composition comprising: a graft copolymer obtained by graft polymerizing an aromatic vinyl-based monomer and a vinyl cyanide-based monomer to an acrylic rubber polymer; a first matrix copolymer comprising a C1-C3 alkyl (meth)acrylate-based monomer unit, an aromatic vinyl-based monomer unit and a vinyl cyanide-based monomer unit; a second matrix copolymer comprising a C1-C3 alkyl (meth)acrylate-based monomer unit, an aromatic vinyl-based monomer unit and a vinyl cyanide-based monomer unit; and an additive comprising a polymer comprising a C1-C3 alkyl (meth)acrylate-based monomer unit, wherein the first matrix polymer and the second matrix polymer have different weight average molecular weights.
