Abstract : Bisbenzimidazobenzophenanthroline-dione (BBB) polymers have been prepared from 1-4-5-8-naphthalene tetracarboxylic acid and 3-3'-diaminobenzidine by polycondensations in polyphosphoric acid. (Polymer structure was verified by elemental and infrared analysis.) BBB polymers were found to be black and amorphous, to have high softening points and to exhibit 600 C stability in N2 by TGA. Intrinsic viscosities ranging from 0.1 to 1.2 dl/gm in sulfuric acid were obtained, the highest viscosity polymers having been produced by reactions near 200 C. Polymers were soluble in strong acid and base could be wet spun from acid solution.
