Title:
THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/043181
Kind Code:
A1
Abstract:
The present invention relates to a thermoplastic resin composition comprising: a diene-based graft polymer; a first polymer including a vinyl cyanide-based monomer unit and an alkyl-substituted styrenic monomer unit; a second polymer including a vinyl cyanide-based monomer unit, a vinyl aromatic-based monomer unit, and a (meth)acrylate-based monomer unit; a third polymer including a vinyl cyanide-based monomer unit and an alkyl unsubstituted styrene-based monomer unit and having a weight average molecular weight of 80,000 to 220,000 g/mol; a fourth polymer including a vinyl cyanide-based monomer unit and an alkyl unsubstituted styrene-based monomer unit and having a weight average molecular weight of 1,500,000 to 5,000,000 g/mol; and a fifth polymer including an olefinic monomer unit and having a density of 970 to 1,000 kg/m3 as measured according to ASTM D1505, wherein the content of the fifth polymer is 0.10 to 3.00 parts by weight with respect to 100 parts by weight in total of the diene-based graft polymer, the first polymer, the second polymer, the third polymer, and the fourth polymer.
