反応手順
Into a 2 liter round bottom flask 800 ml of ethanol, 12.8 g of sodium hydroxide pellets and 80 g of a copolymer composed of 70% N-vinylpyrrolidone and 30% vinyl acetate are introduced. The resulting reaction mixture is maintained with stirring at 30° C. for 2 hours and is then poured into 8 liters of diethyl ether to precipitate the desired polymer. After filtration the polymer is dried under reduced pressure. Yield: 95%.
