The preparation of Example 1 is repeated with the exception that 54 g (0.55 mole) maleic anhydride is copolymerized with 39 g (0.45 mole) methacrylic acid in the presence of 23 g benzoyl peroxide initiator and 95 g 2-butanone (boiling point 80° C.) as solvent, the methacrylic acid is added continuously over a 5-hour period, the refluxing is continued for 10 minutes following the methacrylic acid addition and the copolymer is hydrolyzed by the addition of 210 g water at reflux temperature. A substantially homogeneous methacrylate/maleate copolymer similar to the product of Example 1 is obtained.
