実験手順
A three-necked flask having a capacity of 500 ml was charged with 240 g of methyl ethyl ketone and the content was stirred at 65° C in a nitrogen gas stream. A mixture of 93.74 of styrene, 26.64 g of 4-vinylbenzenesulfonic acid cyclohe ester and 1.99 g of 2,2′-azobis(2,4-dimethylvaleronitrile) was dropwise added thereto over 2 hours. After completion of the dropwise addition, 0.5 g of 2,2′-azobis(2,4-dimethylvaleronitrile) was further added, followed by stirring for further 2 hours, thereby a styrene-4-vinylbenzenesulfonic acid cyclohexyl ester copolymer was obtained. After the reaction mixture was poured into an egg-plant type flask having a capacity of 1 liter and concentrated, 300 g of MFG was added thereto, the reaction mixture was heated for 3 hours with refluxing MFG, thereby sulfonic acid cyclohexyl ester was decomposed to obtain a sulfonic acid. The obtained reaction mixture was cooled to room temperature and poured into a beaker containing 3 liters of water, thus an aqueous solution of a high molecular compound was prepared.
