Title:
METHOD FOR PRODUCING HYDROCARBON GROUP-CONTAINING VINYL ETHER POLYMER BY MEANS OF RADICAL POLYMERIZATION
Document Type and Number:
WIPO Patent Application WO/2020/021902
Kind Code:
A1
Abstract:
[Problem] To provide a stable and efficient method for producing a hydrocarbon group-containing vinyl ether polymer, which is capable of suppressing decomposition of monomers and generation of polyacetals.
[Solution] A method for producing a hydrocarbon group-containing vinyl ether polymer according to the present invention comprises a step wherein a vinyl ether represented by formula (1) (wherein R1 represents an aliphatic hydrocarbon group having 1-10 carbon atoms or an alicyclic hydrocarbon group having 3-10 carbon atoms) is polymerized at a pH of 6 or more in the presence of water that serves as a polymerization solvent and an organic azo compound that serves as a radical polymerization initiator.
