Abstract

It was shown for the first time, that after IR heating of polyphenoxazine in the presence of cobalt(II) acetate Co(CH3CO2)2·4H2O in the inert atmosphere at the temperature of 450–650 °C, the growth of the polymer chain via the condensation reaction of phenoxazine olygomers happens simultaneously with the dehydrogenation of phenyleneamine structures with the formation of conjugated C=N bonds. Hydrogen emitted during these processes contributes to the reduction of Co2+ to Co0.
