Document Type and Number:

Japanese Patent JP6891663

Kind Code:

B2

Abstract:

To provide a thermoplastic methacrylic acid ester resin composition excellent in impact resistance as well as transparency and fluidity, and a molded article thereof.SOLUTION: There is provided a copolymer (A) obtained by polymerizing a vinyl monomer mixture (m1) containing an aromatic vinyl compound, a vinyl cyanide compound, and a macro monomer, in which the macro monomer has polymethacrylic acid ester as a main skeleton and a vinyl group at one terminal of the polymethacrylic acid ester. There is provided a thermoplastic resin composition containing the copolymer (A) and a methacrylic acid ester resin (B) obtained by polymerizing a vinyl monomer mixture containing methacrylic acid ester (m2). There is provided a thermoplastic resin composition further containing a graft copolymer (C) by graft polymerization of a vinyl monomer mixture (m3) containing the aromatic vinyl compound, the vinyl cyanide compound to an ethylene α-olefin copolymer (D). There is provided a molded article by molding the thermoplastic resin.SELECTED DRAWING: None
