Polydiimidazopyridine was synthesized from 2,3,5,6-tetraaminopyridine and 2,5-dihydroxyterephtalatic acid in polyphosphoric acid and characterized. Polydiimidazopyridine possesses high viscosity, high thermal oxidation resistance and excellent film-forming properties. The polymer was processed from reaction mixture in polyphosphoric acid into proton conducting membranes. The membranes possess higher proton conductivity than for many known membranes at 20-200 °C.
