실험 절차

First, 2-sulfobenzaldehyde sodium salt (manufactured by Tokyo Chemical Industry Co., Ltd.) was subjected to ion exchange by use of ion exchange resin (15JWET [trademark], manufactured by Organo Corporation), so that sodium ions were removed to obtain 2-sulfobenzaldehyde. Independently, 50.0 g of 15 wt % PA100 aqueous solution was placed in a three-necked round flask, and then stirred. After the temperature of the solution was adjusted at 24° C., 1.2241 g of the obtained 2-sulfobenzaldehyde was added and then stirred for 12 hours, to obtain the aimed polymer PA121. The obtained polymer was analyzed by means of NMR. As a result, it was verified that 5 mol % of all amino groups in PA100 before substitution were replaced with 2-sulfobenzimino groups.
