The present invention provides a high-purity arylsulfonic acid amine salt vinyl monomer which is an extremely industrially useful arylsulfonic acid monomer with excellent storage stability and amphiphilic solubility in both water and organic solvents, a simple and practical method for producing the same, a polyarylsulfonic acid amine salt which is a polymer thereof, and a method for producing the same. In the arylsulfonic acid amine salt vinyl monomer, a tertiary amine having 2 or 3 different substituents that each have 1 to 7 carbon atoms and also containing at least one or more of tertiary carbon or quaternary carbon or cyclic skeleton in the structure is applied to an amine moiety thereof, and in addition, a polyarylsulfonic acid amine salt having high purity in terms of sulfonation rate and polymerization conversion rate and a polymer thereof are used.
本发明提供了一种高纯度的芳基磺酸胺盐乙烯基单体,它是一种极具工业用途的芳基磺酸单体,在水和有机溶剂中都具有极佳的贮存稳定性和两性溶解性;本发明还提供了一种简单实用的生产芳基磺酸胺盐乙烯基单体的方法、一种作为其聚合物的聚芳基磺酸胺盐以及生产聚芳基磺酸胺盐乙烯基单体的方法。在芳基磺酸胺盐乙烯基单体中,将具有 2 或 3 个不同取代基的叔胺(每个取代基都具有 1 至 7 个碳原子)应用于其胺分子,该叔胺在结构上还至少含有一个或多个叔碳或季碳或环状骨架,此外,还使用了在磺化率和聚合转化率方面具有高纯度的聚芳基磺酸胺盐及其聚合物。
