## Abstract This paper presents an NMR study of the dynamic processes related to proton transport in a new polymer consisting of two blocks – poly(2,6‐diphenylphenol) (P3O) and an imidazole functionalised poly(2,6‐dimethylphenol) (imi‐PPE) – and subsequently doped with polyphosphoric acid (PPA). Fr
## Abstract 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 proces
