It has become possible to reuse it. Further, the composition of the present invention has a characteristic that the viscosity is higher than that of the existing fluorine-containing ion exchange resin alcohol solution, and further, the larger the number of fluorine atoms in the fluorine-containing compound molecule to be mixed, the higher the viscosity. Therefore, it is possible to adjust the viscosity for the same concentration of the ion exchange resin solution by selecting the fluorine-containing compound. At present, the solution of fluorine-containing ion exchange resin is used as a chemically stable catalyst by being supported on a carrier or formed into a film, but it is thought that the application will be further expanded by facilitating the adjustment of viscosity.
