Abstract
The production method for a vinyl ether polymer of the present technology comprises the step of subjecting a vinyl ether monomer to radical polymerization in a mixed solvent to form a vinyl ether polymer. The mixed solvent is a mixed solvent in which the mass ratio of isopropyl alcohol to dimethylformamide is from 93:7 to 75:25, or a mixed solvent in which the mass ratio of isopropyl alcohol to water is from 50:50 to 5:95, and a mass ratio of the vinyl ether monomer to the mixed solvent is from 3:100 to 45:100.
