The polymers were characterized by Fourier transform infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, liquid chromatography/mass spectrometry, thermogravimetric analysis and the elemental analysis. Direct current conductivity of HCl acid-doped polybenzimidazole pellets was measured by applying a constant voltage of 5 V. The results of this study are discussed herein.en10.1177/0954008307087290info:eu-repo/semantics/closedAccessPolybenzoxazolesaromatichydroxamoyl chlorideconductivityArticle206615626Q3WOS:000260840300005Q3
