Popis: Di(benzamido)-substituted poly(diphenylene ketone) is synthesized by the Ni-catalyzed homopolycondensation of previously unknown 4,4′-dichloro-3,3′-di(benzamido)benzophenone. The cyclodehydration of this polymer conducted in poly(phosphoric acid) in the presence of Eaton’s reagent yields organosoluble diphenyl-substituted poly(diazapyrene ketone) possessing high thermal characteristics.
