Phase Transitions and Structure Changes in Poly(bis(Phenoxy)Phosphazene) -PBPP

Abstract

Phase transition behavior in PBPP has been studied by electron microscopy, x ray diffraction techniques and differential scanning calorimetry. Thermal analysis has provided the relative enthalpy change associated with the thermotropic transition, T(1), as a function of heat treatment. The structural and morphological changes corresponding to the enthalpy change have been established. Keywords: Poly (bis (phenoxy) phosphazene), Crystalline modifications, Thermal relationships, Phosphazenes.
