To obtain benzodioxazole analogs of the polypyromellitimides and polymers with alternating pyromellitimide and benzodioxazole links, we have synthesized 2,6-di(paminophyl)benzo[1,2-d∶5,4-d′]dioxazole (I), 2,6-di[p-(p′-aminophenoxy)phenyl]benzo-[1,2-d∶5,4-d′]dioxazole (II), N,N′-di(p-chloroformylphenyl)pyromellitdiimide (III) and N,N′-di(p-chloroformylphenyl)-2,5-dimethoxycarbonyl terephthalamide (IV). Derivatives modelling the polymers mentioned above have been synthesized from the diamines mentioned, and also from 4,6-diaminoresorcinol.
