Title:
STYRENE-BASED THERMOPLASTIC RESIN COMPOSITION, PRODUCTION METHOD OF STYRENE-BASED THERMOPLASTIC RESIN COMPOSITION, MOLDED ARTICLE, AND PRODUCTION METHOD OF MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2020/188978
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a styrene-based thermoplastic resin composition having not only excellent impact resistance but also good fluidity. The present invention pertains to a styrene-based thermoplastic resin composition comprising: a graft copolymer (A) obtained by graft–polymerizing, in the presence of a conjugated diene rubbery polymer, a monomer mixture (a) containing at least an aromatic vinyl-based monomer, a methacrylic acid ester-based monomer, and an acrylic acid ester-based monomer; and a vinyl-based copolymer (B) obtained by copolymerizing a monomer mixture (b) which contains an aromatic vinyl-based monomer, a methacrylic acid ester-based monomer, and a vinyl cyanide-based monomer and does not substantially contain an acrylic acid ester-based monomer.
