| Abstract | Abstract : The kinetics of isothermal crystallization of two polyphosphazene polymers, poly(bis(trifluoroethoxy)phosphazene) and poly(bis(phenylphenoxy)phosphazene), have been studied utilizing a modified differential scanning calorimeter (DSC) technique and the depolarized light intensity (DLI) technique. The kinetics of transformation of both and isotropic to 2-D pseudohexagonal mesophase as well as the mesophase to 3-D orthorhombic phases have been measured and analyzed using Avrami theory. Classical nucleation theory has been utilized for estimating values of the surface free energies of the nuclei during crystallization. Keywords: Phenyl radicals. (MJM) |
