The preparation of polyphosphazene random and block copolymers bearing trifluoroethoxy and alkoxyalkoxy groups by the anionically initiated polymerization of phosphoranimines and poly(diarylphosphazene)s from phosphine azide intermediates is discussed. The properties of these materials were studied by differential scanning calorimetry, wide‐ and small‐angle X‐ray scattering, thermogravimetric analysis, dynamic mechanical analysis, dielectric relaxation spectroscopy, single crystal X‐ray and electron diffraction, density measurements and optical microscopy, and were correlated with molecular architecture, molecular weight, composition and side groups structure.
