| Abstract: | In this work,polybenzimidazole(PBI) is synthesized by polycondensation of 3,3',4,4'-tetraminobiphenyl(TAB) and isophthalic acid(IPA) with temperature increasing gradually. The products are characterized by FT-IR,1H-NMR and thermogravimetric analysis. Simultaneously,the influence of several parameters that seem to affect the polycondensation is studied,reaction conditions are optimized. Likewise,the solubility of PBI and its derivatives poly(2,5-benzimidazole)(ABPBI) in different solvent is also discussed. |
