The present invention provides a high-purity arylsulfonic acid amine salt that has both excellent storage stability and amphiphilicity that is soluble in both water and organic solvents, and is an industrially extremely useful arylsulfonic acid monomer A vinyl monomer and a simple and practical production method thereof, and a polyarylsulfonic acid amine salt which is a polymer of the arylsulfonic acid amine salt vinyl monomer, and a production method thereof. In the arylsulfonic acid amine salt vinyl monomer, in which a tertiary amine having two or three different substituents having 1 to 7 carbon atoms is applied at the amine site, a tertiary carbon or a quaternary carbon is contained in the structure or As at least one or more tertiary amines in the cyclic skeleton, in terms of sulfonation rate and polymerization conversion rate, high-purity arylsulfonic acid amine salts and polymers thereof are used. |
