Polybenzimidazole (PBI) in beaded form (250-500 mikrometrs) has been characterized in the dry state by scanding electronmicroscopy (SEM), BET, and nitrogen porosimetry. In the swo-llen state, in has been characterised by inverse steric ex-clusion chronomatography (ISEC) in tetrahydrofuran, toluene,and water, by ESR of TEMPONE (2,2,6,6-tetramethyl-4-oxo-1-oxypiperidine), and pulse field gradient spin echo (PGSE)NMR spectroscopy, in the latter two cases in tetrahydrofuran,ethanol and water.
