Reaktionsschritte

In 59.69 g of methanol were dissolved 18.43 g (68.43 mmol) of 11-methacrylamidoundecanoic acid (MAU), 1.57 g (7.60 mmol) of N,N-dimethylaminopropylacrylamide methyl chloride (Kohjin Co., Ltd.), 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 obtained solution was dropwise added into a large excess of acetone, and the resulting precipitate was collected by filtration under suction. After drying under reduced pressure, 9.60 g of random MAU/N,N-dimethylaminopropylacrylamide methyl chloride copolymer (90/10) was obtained (yield: 48.0%). The weight average molecular weight was 42000.
