The photolysis of poly[bis( p ‐tolylamino)]phosphazene has been studied in methylene chloride solution. The main reactions observed were chain scission and crosslinking. The dissociation into radicals of polyphosphazene is proposed as the primary act of the photolysis. This has been substantiated by the results of the photolysis carried out in the presence of both radical scavengers and some benzophenones as sensitizers.
