PROCESS FOR PRODUCING VINYL ETHER POLYMER HAVING HYDROXY GROUPS IN SIDE CHAINS, AND TEMPERATURE-RESPONSIVE POLYMER MIXTURE

摘要

[Problem] To provide a process for producing a vinyl ether polymer having hydroxy groups in side chains, the process being capable of easily and efficiently producing the vinyl ether polymer which has a low viscosity and is excellent in terms of operation efficiency and processability.[Solution] The present invention is a process for producing a vinyl ether polymer having hydroxy groups in side chains, and is characterized in that a vinyl ether containing a hydroxy group is subjected to radical polymerization in the presence of a mixed solvent comprising water and an organic solvent selected from among alcohols and cyclic ethers , using an oil-soluble azo polymerization initiator.
