Abstract

N1,N4-diphenyl-1,2,4,5-tetraaminobenzene was condensed with the di-acid chlorides of terephthalic acid, isophthalic acid and 2,5-pyridine-dicarboxylic acid in polar aprotic solvent to give the poly(o-phenylamino)amides which, after cyclodehydration in polyphosphoric, acid gave three new N,N'-diphenyl substituted polybenzimidazoles (PBI). The syntheses and certain of the solution and thermal properties of the PBI's are discussed. The synthesis of three new tetraamine monomers and their related model compounds is also described.
