✦ Synopsis
The photodegradations of poly-[bis(fl-naphthoxy)] phosphazene and poly-[bis(p-tolylamino)] phosphazene were investigated in methylene chloride solution. A mechanism has been proposed to explain the influence of molecular oxygen on the photoprocesses. Molecular weight variations, results of flash photolysis experiments and the observed post-photochemical effect are in agreement with the suggested mechanism.
