Abstract

2,5‐Diamino‐3,6‐dichloro‐1,4‐benzoquinone (chloranilamide) condensates, under generation of HCl, above 300°C to form polychloranilamide. The reaction was studied by thermovolumetric measurements, especially in the presence of different metal salts (cobalt, iron and manganese). The composition of the brittle black polymers is as expected, and the IR spectra resemble to those of the corresponding model compounds based on 5,8‐dihydroxyquinoxaline. Their electrical conductivity is 10^−8^ – 10^−5^ S · cm^−1^. Metal contents of up to 25 wt.‐% were achieved corresponding to 80% of the theoretical value. The metal complexes are not stable against acids, and the compounds are not very resistant in a strongly alkaline milieu. Nevertheless, they could be promising, e.g., as ion exchangers, as precursors for organic materials with high metal contents such as catalysts, or as model compounds for similar polymers.
