Abstract
An acrylic rubber graft copolymer is obtained by graft polymerizing a vinyl monomer in the presence of a rubbery polymer including acrylate ester monomer units and polyfunctional monomer units, wherein the total amount of the polyfunctional monomer units in the rubbery polymer is 0.3 to 3 parts by mass with respect to 100 parts by mass of the acrylate ester monomer units, and the polyfunctional monomer units include 30 to 95 mass % of polyfunctional monomer units having two unsaturated bonds and 5 to 70 mass % of polyfunctional monomer units having three unsaturated bonds with respect to 100 mass % of the total of the polyfunctional monomer units. A thermoplastic resin composition includes the acrylic rubber graft copolymer.
