Patent ID: 11286371

Abstract:
Provided is a thermoplastic resin composition excellent in heat resistance, transparency, appearance after shaping, and weather resistance, and in which coloring is suppressed during shaping processing. The thermoplastic resin composition of the present invention includes a copolymer (P1), and an antioxidant (O) represented by General Formula (1), in which the thermoplastic resin composition contains 80% by mass or more of the copolymer (P1) with respect to a total mass of the thermoplastic resin composition, and the copolymer (P1) includes 80 mol % or more of a repeating unit (A) derived from methyl (meth)acrylate (a), 2 mol % or more and 7 mol % or less of a repeating unit (B) derived from (meth)acrylic acid (b), and 0.001 mol % or more and 0.15 mol % or less of a repeating unit (C) having a glutaric anhydride structure.
