Title:
HIGH-PURITY AMPHIPATHIC ARYLSULFONIC ACID AMINE SALT VINYL MONOMER AND COPOLYMER THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/031454
Kind Code:
A1
Abstract:
Provided are: a high-purity arylsulfonic acid amine salt vinyl monomer which has both of excellent storage stability and amphipathicity such that the monomer is soluble in both of water and an organic solvent and which is an extremely industrially useful arylsulfonic acid monomer; a method for producing the monomer in a simple and practically efficient manner; a polyarylsulfonic acid amine salt which is a polymer of the monomer; and a method for producing the amine salt. Among tertiary amines each containing two or three different substituents each having 1 to 7 carbon atoms at the amine site thereof in arylsulfonic acid amine salt vinyl monomers, a tertiary amine having at least one tertiary or quaternary carbon atom or cyclic backbone in the structure thereof is applied. In addition, a polyarylsulfonic acid amine salt that is highly pure with respect to a sulfonation rate and a polymerization conversion rate and a polymer of the monomer are used.
