Synthesis and Characterization of Pyridine‐Based Polybenzimidazoles for High Temperature Polymer Electrolyte Membrane Fuel Cell ApplicationsAbstract A series of polybenzimidazoles (PBIs) incorporating main chain pyridine groups were synthesized from the pyridine dicarboxylic acids (2,4‐, 2,5‐, 2,6‐ and 3,5‐) and 3,3′,4,4′‐tetraaminobiphenyl, using polyphosphoric acid (PPA) as both solvent and polycondensation reagent. A novel process, termed the PPA process, has been developed to prepare phosphoric acid... ...
