Ultraviolet functionalization of poly[bis(4-isopropylphenoxy)]phosphazene surfaces: An infrared and a sims study

Abstract Films of poly[bis(4-isopropylphenoxy)phosphazene] (PIPP) have been irradiated in air with u.v. light, and the exposed polymer surface investigated by i.r. spectroscopy and secondary ion mass spectrometry. Evidence is given that light-generated hydroperoxides are formed mainly on the tertiary carbons of the isopropylic groups in the polyphosphazene. These functions may be used for surface functionalization studies of PIPP.
