The invention relates to a method for producing an anion-exchange polymer material having an IPN or semi-IPN structure, said method consisting in: (A) preparing a homogeneous reaction solution containing, in a suitable organic solvent, (a) at least one organic polymer bearing reactive halogen groups, (b) at least one tertiary diamine, (c) at least one monomer comprising an ethylenic unsaturation polymerizable by free radical polymerization, (d) optionally at least one cross-linking agent including at least two ethylenic unsaturations polymerizable by free radical polymerization, and e) at least one free radical polymerization initiator; and (B) heating the prepared solution to a temperature and for a duration that are sufficient to allow both a nucleophilic substitution reaction between components (a) and (b) and a free radical copolymerization reaction of components (c) and optionally (d) initiated by component (e). The invention also relates to the resulting IPN or semi-IPN material and to the use thereof i
