Title: Poly(phenylene alkylene)-based lonomers

Abstract

A composition and method of forming a composition including a compound including a poly(phenylene) backbone represented by the following formula: ##STR00001## wherein each of R.sub.1, R.sub.2 and R.sub.3 may be the same or different and is H or an unsubstituted or inertly-substituted aromatic moiety; wherein Ar.sub.1 is an unsubstituted or inertly-substituted aromatic moiety; wherein R.sub.4 is an alkylene, perfluoroalkyl, polyethylene glycol, or polypropylene glycol moiety; wherein each of R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10 and R.sub.11 is H or a monovalent hydrocarbon group including two to 18 carbon atoms, with the proviso that each R.sub.6, R.sub.7, R.sub.8, R.sub.9, R.sub.10 and R.sub.11 cannot be H; and wherein each of Y.sub.6, Y.sub.7, Y.sub.8, Y.sub.9, Y.sub.10 and Y.sub.11 may be the same or different and is H or a functional group are disclosed. The composition can be used as anion-exchange membranes and as an electrode binder material in anion exchange membrane fuel cells.
