Aminoethanol is reacted with a fluoroalkylsulfonic anhydride to obtain a fluoroalkylsulfonylaminoethanol (first step: sulfonylamidation step). The fluoroalkylsulfonylaminoethanol is esterified with an α-substituted acrylate derivative to obtain a desired fluoroalkylsulfonylaminoethyl α-substituted-acrylate (second step: esterification step). Thus, the desired fluoroalkylsulfonylaminoethyl α-substituted-acrylate having a higher purity can be produced in higher yield with higher operating efficiency than in conventional techniques.
Novel molten-salt type polyelectrolytes are disclosed which contain as an essential ingredient a molten salt polymer obtained by reacting an imidazolium derivative, such as a 1,3-dialkylimidazolium halide, 1,2,3-trialkylimidazolium halide, 1-vinyl-3-alkylimidazolium halide, or 1-vinyl-2,3-alkylimidazolium halide, with an acid monomer, a poly(vinylsulfonamide), trifluoromethanesulfonimide, or the like. The electrolytes show high ionic conductivity at room temperature and have excellent stability to temperature fluctuations and excellent mechanical properties.
