✦ Synopsis

The vibrational spectra of a new type of phosphazene polymer, (polyspirophosphazene), are

) ] n discussed. The spectra were recorded for powders dispersed in KBr pellets and for Ðlms prepared from di †erent solvents. The IR spectra are dominated by the vibrational modes of the main chain whereas the Raman spectra are dominated by the vibrations of the peripheral biphenyl groups. The full width at half maximum (FWHM) of the Raman band at 1609 cm-1, corresponding to one of the CC stretching modes of the biphenyl, decreases with increase in the degree of crystallinity of the polymer sample. 1998
