Reaktionsschritte

In 59.68 g of methanol were dissolved 18.80 g (69.82 mmol) of 11-methacrylamidoundecanoic acid (MAU), 1.20 g (7.76 mmol) of 2,2,2-trifluoroethyl acrylate (Tokyo Chemical industry Co.), and 0.32 g (1.95 mmol) of azoloisisobutyronitrile (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, 9.02 g of random MAU/2,2,2-trifluoroethyl acrylate copolymer (90/10) was obtained (yield: 45.1%). The weight average molecular weight was 35000.
