Title:
ACRYLIC RUBBER-BASED GRAFT COPOLYMER AND THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2012/133190
Kind Code:
A1
Abstract:
[Problem] To provide an acrylic rubber-based graft copolymer capable of providing a thermoplastic resin composition of which impact resistance, stiffness, and external appearance are all excellent, and to provide a thermoplastic resin composition including the acrylic rubber-based graft copolymer. [Solution] An acrylic rubber-based graft copolymer that is a graft copolymer formed by graft polymerization of a vinyl monomer in the presence of a rubber polymer including acrylic ester-based monomer units and polyfunctional monomer units, wherein the total volume of the polyfunctional monomer units in the rubber polymer is 0.3-3 parts by mass with respect to 100 parts by mass of the acrylic ester-based monomer units, and 30-95% by mass of polyfunctional monomer units having two unsaturated bonds and 5-70% by mass of polyfunctional monomer units having three unsaturated bonds are included in the total volume of 100% by mass of the polyfunctional monomer units. A thermoplastic resin composition including the acrylic rubber-based graft copolymer.
