Notes:
The polymerization reaction of tris(o-phenylenedioxy)cyclotriphosphazene, [NP(O2C6H4)]3, occurs in the ion chamber of a mass spectrometer under high-sample vapour pressure conditions, leading to the formation of tetrameric, pentameric and hexameric species. There is evidence that, under electron impact conditions, the phosphonitrilic ring of [NP(O2C6H4)]3 breaks down, giving rise to a linear phosphazene radical cation, from which the polymerization reaction takes place by means of successive additions of neutral NP(O2C6H4) units. A comparison is made between this reaction and mass spectrometrically induced polymerizations of hexachloro- and hexa(phenoxy)-cyclophosphazenes, previously reported.
