ABSTRACT:
A polymer comprising polycyclic repeating units having recurring ion conducting groups and optional crosslinkable groups is disclosed. The present invention provides the capability of tailoring polymers to impart unique properties to membranes fabricated from the polymers. Membranes comprising the polymers and methods for preparing the membranes and their use in ion conducting membranes, particularly in fuel cells, are also provided.
