Species that combine the properties of organosilicon compounds and phos-phazenes are prepared by the linkage of organosilicon side groups to a small molecule cyclic or linear high polymeric phosphazene skeleton. This is particularly important for high polymeric derivatives in which hybrid properties typical of polysiloxanes (silicones) and polyphosphazenes - may be obtained. 

Although a variety of organosilicon groups have been linked to phos- 

All reactions and manipulations are carried out under a nitrogen atmosphere up to the point at which the trifluoroethoxy groups have been attached to the phosphazene skeleton. The glassware used during Grignard and trifluoroethoxide reactions is dried in an oven at 130° for 24 hr and is cooled under vacuum or nitrogen before use.
