実験手順

In a 10 liter flask equipped with a stirrer, a capacitor and a dropping device, 3,500 g of ethanol was charged and heated to 70° C. Then, 440.5 g (4.08 mol) of a vinylphosphonic acid monomer, 1159.5 g (16.31 mol) of acrylamide and 52 g of AIBN were dissolved in 1,000 g of ethanol and the obtained solution was added dropwise in a reactor over 4 hours. During the dropwise addition of a monomer solution, a white precipitate was produced. After heating and stirring for 2 hours while maintaining at 70° C., heating was stopped and the reaction solution was cooled to room temperature. The precipitate thus produced was collected by filtration under reduced pressure and then washed with 1,000 g of ethanol. The precipitate was vacuum-dried at 40° C. for 24 hours to obtain a white fine crystal. Yield: 1,550 g
