<p>A process for producing a copolymer having succinimide units represented by general formula (I) is provided which comprises reaction of a copolymer constituted of 40 - 60 mole % of maleic anhydride units, 60 - 40 mole % of olefin units, and 0 - 20 mole % of another copolymerizable monomer units with an amine to convert the maleic anhydride units to the succinimide units, wherein the succinimide units are formed by ring-closing imidation in a slurry state in a poor solvent: <CHEM> where R1 is a hydrogen atom, or an alkyl or cycloalkyl group of 1 to 6 carbons. The copolymer has low yellowness and high transparency.</p> |
