In addition, the degradation reaction of the 2‐azido‐5‐nitrobenzoyl group in P‐II‐A and the transformation of the 4‐azido‐3‐nitrobenzoyl group to 5‐carboxylbenzofurazane‐1‐oxide ring in P‐II‐B by irradiation with ultraviolet (UV) light or by heating were investigated in detail. In the photochemical reaction the reaction of the azide group in P‐II‐A was affected by the presence of a spacer in the polymer chain.
