Synthesis and characterization of cross-linked poly(arylene ether ketone) containing pendant quaternary ammonium groups for anion-exchange membranes

▸ A novel biphenol monomer containing tertiary amine groups was prepared. ▸ Poly(arylene ether ketone) copolymer containing tertiary amine groups was developed. ▸ Cross-linked quaternized poly(arylene ether ketone)s membranes were synthesized. ▸ The cross-linked membranes exhibit high ion conductivity and low water swelling.
