Abstract
Abstract Poly( N -arylenebenzimidazole pyridine sulfone) (PNABIPS) has been prepared via the aromatic nucleophilic displacement reaction of 2,6-bis(2-benzimidazoly)pyridine (BBP) with bis(4-fluorophenyl) sulfone. BBP was synthesized by reaction of 2,6-pyridinedicarboxylic acid with 1,2-phenylenediamine in polyphosphoric acid. The chemical structure of BBP was confirmed by FT-IR, HRMS, 1 H NMR and 13 C NMR. The characterization of the polymer was performed with FT-IR, 1 H NMR, elemental analysis, GPC, XRD, DSC, TGA and solubility tests. The polymer was obtained in quantitative yield with M n value 12,600 and M w value 28,300, respectively. DSC and TGA measurements show that the glass transition temperature ( T g ) is 312 °C and 5% weight loss temperature is 434 °C in nitrogen and 545 °C in air, respectively. In addition, the novel polymer exhibits good solubility, which can be dissolved in common organic solvent at room temperature.
