Thermal degradation products of nitrogen‐containing polymeric materials were analysed for hydrogen cyanide. A spectrophotometric method was used for the determination of cyanides using the formation of a characteristic absorption peak of cyanonickel(II) ion in the ultraviolet spectral region. Pyrolysis and thermooxidation products were studied and conclusions on the reproducibility of the degradation process were drawn. The effect of temperature on the quantity of hydrogen cyanide formed was studied as well.
