Procedure

To a separable flask equipped with a condenser having an inside volume of 2,000 ml, 20 g of sodium 2-sulfoethyl methacrylate, 10 g of potassium methacrylate, 170 g of methyl methacrylate, 350 g of tetrahydrofuran, 350 g of methanol, and 100 g of deionized water were introduced and stirred under nitrogen atmosphere. To this mixture, 1.5 g of 2,2′-azobis(2,4-dimethylvarelonitrile) was added as a polymerization initiator and the resultant mixture was heated to 60° C. After the mixture was stirred for 6 hours, a transparent polymer solution was obtained. During the polymerization, the polymerization solution was kept homogeneously and deposition or precipitation of a polymer or cloudiness of the polymerization solution was not observed. After the mixture was cooled at a room temperature, the mixture was subjected to reprecipitation treatment with isopropanol to recover white powder, and the resultant white powder was dried with a vacuum dryer at 40° C. to obtain (meth)acrylic polymer (1).
