Procedure

Along with 228 mg (0.08 mmol) of poly(1-vinyl-2-pyrrolidone) macroinitiator prepared in Example 67, 3.3 mg (0.02 mmol) of 2,2′-azobis(isobutyronitrile) and 1.04 g (8.1 mmole) of n-butyl acrylate (same as above) were placed into a glove box with the inside air replaced by nitrogen, followed by stirring at 60° C. for 6 hours. After the completion of the reaction, the reaction mixture was dissolved in 5 ml of N,N-dimethylformamide (DMF), and the solution was then poured into 300 ml of hexane which was being stirred. The resulting polymer precipitate was collected by suction filtration and dried to obtain block copolymer of poly(1-vinyl-2-pyrrolidone-b-n-butyl acrylate) (yield 94%).
