## Abstract 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
## Abstract **Summary:** Optically active polyanilines were prepared by an interfacial polymerization with (NH~4~)~2~S~2~O~8~ in a water/perchloric acid/chloroform system. The pristine polymer obtained in this way is in the oxidized (doped) form. The polymers display the mirrorβimage Cotton effect.
