Abstract

Hexakis(2,2,2‐trifluorethoxy)cyclotriphosphazene (1b) reacts with borontrichloride at elevated temperatures to give a mixture of polymeric phosphazenes containing imino dichloro and imino bis(trifluoroethoxy)phosphoranetriyle units. The reaction was investigated by ^31^P NMR. Separation of several fractions of polymers was achieved by hexane/benzene solvent extraction. Molecular weights have been determined by means of membrane and/or vapor pressure osmometry. A reaction mechanism is discussed.

## Abstract Hexachlorocyclotriphosphazene (**1**) reacts with SbCl~5~ or BCl~3~ to produce long chain polymers, whereas AlCl ^3^ gives phosphazenyl cations. TiCl~4~ does not react and boric acid esters lead to an exchange of one ester group for one chlorine. ^31^P NMR‐spectra were used to identify
