Reaction Steps
A reactor equipped with a stirrer, a thermometer and a reflux condenser was charged with 100 parts of dimethylformamide, 40 parts of styrene, 40 parts of maleic anhydride and 20 parts of acrylamide methylpropanesulfonic acid. After dissolution, 5 parts of azobisisobutyronitrile was added to carry out reaction at 80° C.-100° C. for 4 hours, giving a copolymer of styrene, maleic anhydride and 2-acrylamido-2-methylpropanesulfonic acid. The copolymer was isolated by reprecipitation with isopropyl alcohol and dried under reduced pressure.
