実験手順

A 1 L four-necked flask was charged with 230 g of isopropyl alcohol (manufactured by Kishida Chemical Co., Ltd.), 345 g of ion exchanged water, 10 g of styrene (manufactured by Kishida Chemical Co., Ltd.), and 40 g of sodium styrene sulfonate (manufactured by Wako Pure Chemical Industries, Ltd.), and 6.6 g of ammonium persulfate (manufactured by Wako Pure Chemical Industries, Ltd.) was added as an initiator. Of this mixture, 189.4 g (30 wt % of the whole reaction liquid) was transferred to a 200 mL dropping funnel, and added dropwise over six hours at 65±5° C., further aged for two hours, and the solvent was thereafter removed under reduced pressure to give styrene/sodium styrene sulfonate copolymer (33/67 mol %). The weight-average molecular weight of this copolymer was 11000.
