Water soluble polyvinyl alcohol derivative |
| abstract |
A cold water-soluble polyvinyl alcohol derivative comprises 70 to 90 mol% of the vinyl alcohol units, 0 to 2 mol% of the vinyl acetate units and 10 to 30 mol% of the acetalized vinyl alcohol units having an alkyl group having 0.34 to 1.70 carbon atoms on the average, having a viscosity-average polymerization degree of 200 to 500 in respect to the vinyl monomer units. |
