実験手順

A 1 L four-necked flask was charged with 91 g of isopropyl alcohol (manufactured by Kishida Chemical Co., Ltd.), 137 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 the temperature was raised to 83±2° C. After introducing 6.6 g of ammonium persulfate (manufactured by Wako Pure Chemical Industries, Ltd.) as an initiator, the mixture was polymerized for two hours, and further aged for two hours. Thereafter, the solvent was removed under reduced pressure to give styrene/sodium styrene sulfonate copolymer (33/67 mol %). The weight-average molecular weight of this copolymer was 16000.
