Abstract

Ionomers and ionomer membranes, consisting of a non-fluorinated or partly fluorinated non-, partly or fully-aromatic main chain and a non- or partly-fluorinated side chain with ionic groups or their non-ionic precursors, have a positive impact on the proton conductivity of the ionomers. Various processes produce these polymeric proton conductors.
