Highly pure aryl sulfonic acid amine salt vinyl monomer which is an industrially very useful aryl sulfonic acid monomer that has excellent storage stability and amphipathic property soluble in both water and organic solvent, and its simple and practical use. And a polyaryl sulfonic acid amine salt which is a polymer thereof and a method for producing the same. Aryl sulfonic acid amine salt vinyl monomer, tertiary amine having 2 or 3 different substituents having 1 to 7 carbon atoms at the amine site, and tertiary carbon or quaternary carbon or cyclic skeleton in the structure A tertiary amine containing at least one or more is applied, and in addition, a high-purity polyarylsulfonic acid amine salt and its polymer are used in terms of sulfonation rate and polymerization conversion rate. |
