Synthesis of polybenzimidazoles from monomers containing flexible linkages
CIVINS === Polybenzimidazoles were synthesized from 3, 3', 4, 4'- tetraminobiphenyl (diaminobenzidine, or DAB) with orthoesters, carboxylic acid derivatives (an ester and an acid) and with m-benzenedialdehyde. The products were of low molecular weight, as evidenced by low inherent viscosit...
