In 59.69 g of methanol were dissolved 18.47 g (68.60 mmol) of 11-methacrylamidoundecanoic acid (MAU), 1.53 g (7.62 mmol) of 2,2,3,3-tetrafluoropropyl methacrylate (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 diethyl ether, and the resulting precipitate was collected by filtration under suction. After drying under reduced pressure, 16.15 g of random MAU/2,2,3,3-tetrafluoropropyl methacrylate copolymer (90/10) was obtained (yield: 80.8%). The weight average molecular weight was 220000.
