Sulfoned aromatic acid and o-phenylenediamine as the monomers, sulfoned-benzimidazole was obtained by condensation reaction. Poly(aryl sulfone benzimidazole) sulfone (PSBIS) as novel heat-resistant polymer was obtained by the condensation polymerization via Palladium-catalyzed aryl amination reaction of sulfoned-benzimidazole and aromatic dibromide. Differential scanning calorimetry (DSC) and thermal analysis (TG) measurements showed that the polymer synthesized possessed high glass transition temperature (Tg>321°C), good thermal stability with high decomposition temperature (TD>540°C) and good solubility.
