Abstract: Cationic copolymers having pendant N-allylimidazolium-containing groups are provided. The cationic copolymers can be used, for example, to provide anion exchange membranes for use in electrochemical cells such as fuel cells, electrolyzers, batteries, and electrodialysis cells. The anion exchange membranes typically have good mechanical properties and ionic conductivity.

Abstract: A crosslinkable copolymer is provided. The crosslinkable copolymer has pendant cationic nitrogen-containing groups with some, but not all, of these pendant groups further including a (meth)acryloyl group. The (meth)acryloyl groups can react to form a crosslinked copolymer that is ionically conductive. The crosslinked copolymer can be used to provide an anion exchange membrane that can be used in electrochemical cells such as fuel cells, electrolyzers, batteries, and electrodialysis cells.
