反応手順
The preparation of Example 4 is repeated with the exception that 39 g (0.40) mole maleic anhydride is copolymerized with 52 g (0.60 mole) methacrylic acid in the presence of 14 g di-t-butyl peroxide initiator and 945 g diethyl phthalate in a 2000 ml flask, the methacrylic acid is added over a 20-minute period at a polymerization temperature of 150° C., the reaction solution is held at the polymerization temperature for 10 minutes following the methacrylic acid addition, and the copolymer is hydrolyzed by the addition of 420 g water added at a temperature of 120° C. A substantially homogeneous hydrolyzed methacrylate/maleate copolymer is obtained.
