Özet
In this study, a new synthesis of polybenzoxazoles was studied by reacting 3,3'-dihydroxy-4,4'-diaminobiphenyl with various p-aromatic dihydroxamoyl chlorides in N,N-dimethylformamide under a nitrogen atmosphere at both room temperature and 150 degrees C. 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.
