A series of polybenzimidazoquinazolines (PIQ) were prepared by the condensation of 5, 5-bis[2(o-aminophenyl)benzimidazole] with phenyl esters of various di- and tricarboxylic acids. Thermomechanical and thermooxidative properties of the neat resins and as matrices in reinforced composites were ...
Three samples of poly[2,2′-(o-phenylene]-5,5′-bibenzimidazole] (PBI) were prepared by condensation of 3,3′-diaminobenzidine (DAB) with, respectively, phthalic anhydride in p-cresol under NZ, with phthaloyl chloride in a xylene-water system containing carbonate, and with phthalimide in ...
To prepare organo-soluble poly[(2,2,′- m -phenylene)-5,5′-bibenzimidazole] (PBI) with high yield, a homogeneous nitration of PBI was attempted. Nitro-substituted PBI (NO2-PBI) was synthesized through the homogeneous reaction of the PBI powder with nitric acid in sulfuric acid. Th...
