Procedure

A 1 L four-necked flask was charged with 225 g of isopropyl alcohol (manufactured by Kishida Chemical Co., Ltd.), 225 g of ion exchanged water, 15 g of methyl methacrylate (manufactured by Wako Pure Chemical Industries, Ltd.), and 35 g of sodium styrene sulfonate (manufactured by Wako Pure Chemical Industries, Ltd.), and 8.3 g of 2,2′-azobis(2-methylpropionamidine)dihydrochloride (V-50, manufactured by Wako Pure Chemical Industries, Ltd.) was added as an initiator. Of this mixture, 101.6 g (20 wt % of the whole reaction liquid) was transferred to a 200 mL dropping funnel, and added dropwise over two hours at 83±2° C., further aged for two hours, and the solvent was thereafter removed under reduced pressure to give methyl methacrylate/sodium styrene sulfonate copolymer (50/50 mol %) as white powder. The weight-average molecular weight of this copolymer was 15000.
