In 59.69 g of methanol were dissolved 18.15 g (67.41 mmol) of 11-methacrylamidoundecanoic acid (MAU), 1.85 g (7.49 mmol) of potassium 3-methacryloxypropanesulfonate (Tokyo Chemical industry Co.), and 0.31 g (1.89 mmol) of azobisisobutyronitrile (Nacalai Tesque, Inc.). The solution was deaerated by bubbling nitrogen for 60 minutes. The container was covered with a septum, and the polymerization was conducted by heating at 60° C. for 20 hours. After the completion of the polymerization reaction, the reaction solution was dropwise added into a large excess of ethyl acetate, and the resulting precipitate was collected by filtration under suction. After drying under reduced pressure, 18.47 g of random MAU/potassium 3-methacryloxypropanesulfonate copolymer (90/10) was obtained (yield: 92.4%). The weight average molecular weight was 240000.
