## 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

Poly(dianilino phosphazene) has been synthesized from hexachlorocyclotriphosphazene by two different methods, bulk and solution. Several fractions, with polydispersity ratio ranging from 1.8 to 2.4, were obtained by fractional precipitation and characterized by viscometry and size exclusion chromato
## 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
