## Abstract Dielectric properties of poly[bis(trifluoroethoxy)phosphazene] (PFEP) and poly[bis(__m__βmethylphenoxy)phosphazene] (PmMPP) were studied in a temperature range from β195 to 120Β°C and at several frequencies between 0,1 and 100 kHz. In PFEP, two relaxations, an Ξ± relaxation above the glas

## Abstract Well characterized poly[bis(__p__βmethoxyphenoxy)phosphazene] (PB(4βMeO)PP) has been investigated employing Xβray diffraction and differential scanning calorimetry (DSC). The DSC heating scan of the original PB(4βMeO)PP specimen exhibits one exotherm at 110Β°C and two endotherms at 106Β°C
The crystal structure and chain conformation of polyibis(3,4-dimethylphenoxy)phosphazene] -PB(dMe)PP -have been studied by X-ray diffraction techniques. The unit cell of this polymer shows an orthorhombic form with the crystallographic parameters a=2.05, b= 1.49, c (chain axis) =0.998 nm. Its space
