Abstract (en)
[origin: CA3158871A1] The present invention relates to new anion exchange polymers and corresponding (blend) membranes made of polymers containing highly fluorinated groups, by way of nucleophilic substitution, and method for producing same by way of nucleophilic aromatic substitution, and their use in membrane processes, in particular electrochemical membrane processes such as in fuel cells, in electrolysis and in redox flow batteries.
