Abstract
[Object] To provide a method for producing a vinyl ether polymer having a hydroxyl group on the side chain, wherein the vinyl ether polymer having a low viscosity and excellent workability and processability is produced in a simple and efficient method.[Means for solving problem] The present invention relates to a method for producing a vinyl ether polymer having a hydroxyl group on the side chain, characterized in that vinyl ether comprising a hydroxyl group is subjected to radical polymerization by using an oil-soluble azo polymerization initiator, in the presence of a mixed solvent comprising water and an organic solvent selected from alcohol or cyclic ether radical polymerization.
