The degree of alcoholysis has an effect on the water solubility, viscosity, adhesion and serosity of the slurry.1． Water solubility:PVA with fully alcoholysis is poor in water solubility,for example,PVA with Alcoholysis degree more than 99%(Mole fraction) begin to dissolve when it is heated above 9

Since the partially alcoholized PVA contains more acetate groups, and the volume of the acetate group is much larger than the hydroxyl group, there is a large steric hindrance, so that the partially alcoholized PVA cannot form a compact crystal structure. It can only form loose structures with large
