PURPOSE:To produce the titled polymer in good yields, by radical-polymerizing an alpha,beta-unsaturated dicarboxylic acid hydride in the presence of a specified copolymer (derivative) and a poor solvent. CONSTITUTION:A 12C or higher alpha-olefin is radical-copolymerized with an alpha,beta-unsaturated dicarboxylic acid anhydride (e.g., maleic anhydride) at 50-200 deg.C and, if necessary, the product is esterified to obtain an alpha-olefin/alpha,beta-unsaturated dicarboxylic acid copolymer or its derivative (A). To 100pts.wt. alpha,beta-unsaturated dicarboxylic acid anhydride, 0.5-10pts.wt. component A and a poor solvent (B) (e.g., butane) for the formed polymer and 1-30pts.wt. catalyst (C) (e.g., cumene hydroperoxide) are added and the mixture is radical-polymerized at 70-200 deg.C for 2-12hr.
