To obtain an ionic polymer having a high ion exchange capacity and a low moisture content, by simply converting a —SO2F group in a polymer to a pendant group having a plurality of ion exchange groups, while preventing a cross-linking reaction. A process for producing an ionic polymer, which comprises (A) a step of converting a —SO2F group in a polymer to a —SO2NZ1Z2 group (each of Z1 and Z2 which are independent of each other, is a group selected from a hydrogen atom, a monovalent metal element and a trimethylsilyl group), (B) a step of reacting the polymer obtained in the step (A) with FSO2(CF2)2SO2F, and (C) a step of converting a terminal —SO2F group of a side chain in the polymer obtained in the step (B) to an ion exchange group such as a —SO3H group; and an ionic polymer obtained by such a process. |
