The Photochemistry of Poly(methylphenylphosphazene)
Abstract
The photochemical reactions of poly(methylphenyl-phosphazene) (PMPP), a disubstituted poly(phosphazene), have been studied. UV-Irradiation results in chain scission in air-saturated dichloromethane solution, whereas in the absence of molecular oxygen, a bimolecular process, leading to extensive crosslinking and gel formation, predominates. The degradation of PMPP is not inhibited by quenchers of the triplet state. The reactions of PMPP most likely originate from the singlet state. Biphenyl has been identified as a major photoproduct from PMPP both in the presence and absence of molecular oxygen.
