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.
