反応手順
10 g of vinylpyrrolidone/vinyl acetate polymer (Trademark: PVP/VA E-635, GAF Corporation U.S.A.) were introduced into 200 ml of 0.2N NaOH. The mixture was stirred for 2 hours at 60° C., adjusted to neutral with 1N HCl and subjected to ultrafiltration using a thin layer filter (Trademark: UM 10, AMICON, Holland) at 3 atoms. Evaporation under reduced pressure and lyophilization to a temperature of -70° C. to -80° C. gave 8.9 g of vinylpyrrolidone/vinyl alcohol polymer as white powder.
