Abstract
An anion exchange branched co-polymer includes poly(aryl) and a branched compound and quinuclininuium side chains. The co-polymer may include xanthene or bibenzofuran. The anion exchange branched co-polymer may be more durable and have less creep and may have a higher ion exchange capacity (IEC) due to the structure and because some of the side chains may have multiple functional sites. The co-polymer may be cross-linked and may also include free radical inhibitors. The co-polymer may be incorporated into a support material and used in an anion exchange membrane or membrane electrode assembly.
