The present invention is a copolymer containing a maleimide monomer unit and an unsaturated dicarboxylic acid anhydride monomer unit as a constituent, and having an unreacted maleimide monomer and an unreacted unsaturated dicarboxylic acid anhydride monomer having 0.1 ppm or less of 0.1 ppm. To 3,000 ppm of a component of the copolymer, an additive of a compound other than the maleimide monomer and the unsaturated dicarboxylic anhydride monomer, and as a component (a) 15 to 65% by weight of a maleimide monomer At least one 85-35% by weight monomer unit selected from the group consisting of units (A) and (b) aromatic vinyl monomers and other vinyl monomers (total amount of monomer units (a) and (b) is 100% by weight) At least one step selected from the group consisting of 20 to 90 parts by weight of the maleimide copolymer (B), an aromatic vinyl monomer and other vinyl monomers comprising 10 ppm or less of unreacted maleimide monomer, comprising a thermoplastic resin composition comprising 80 to 10 parts by weight of a graft polymer (C) obtained by polymerizing a sieve in the presence of a rubber polymer, and 0 to 100 parts by weight of other thermoplastic resins. In addition to the maleimide monomer, a total volatilization amount of 0.5% by weight or less, and components of the maleimide copolymer and 0.1 to 3,000 ppm of an additive other than the maleimide monomer are contained, and the composition of the copolymer The present invention relates to a copolymer or a thermoplastic resin composition characterized by adding a compound other than the component, and a method for producing the same. |
