The present invention provides a maleimide copolymer, a manufacturing method therefor, and a resin composition using the same. This maleimide copolymer has 40-60mass% of an aromatic vinyl monomer unit, 5-20mass% of a vinyl cyanide monomer unit, 25-50mass% of a maleimide monomer unit, and 0.1-10mass% of a dicarboxylic acid anhydride monomer unit, has a glass transition temperature of 165°C or greater, and has 1-30 dicarboxylic acid anhydride monomer units included in one copolymer molecule. Also provided is a resin composition that is obtained by kneading and mixing the maleimide copolymer and one or more types of resin selected from ABS resins, ASA resins, AES resins, and SAN resins, and has a superior balance of the physical properties of surface gloss, heat resistance, impact resistance, and fluidity. |
