Abstract
The invention relates to an anion-exchange membrane (AEM) having a multiblock copolymer including a hydrophilic norbornene-based monomer and a hydrophobic alkene-based or norbornene-based monomer. The hydrophilic norbornene-based monomers include one or more cationic head groups such as a quaternary ammonium ion, which can optionally be crosslinked with a crosslinking agent to increase the structural stability of the polymer. These AEMs can be employed in electrochemical devices such as fuel cells.
