Phosphazene polymers having the units <IMAGE> <IMAGE> wherein the total number of units ranges from about 3 to about 50,000, R1 and R2 are different and are C1 to C12 linear or branched alkyl, C2 to C15 linear or branched fluoroalkyl or mixtures thereof, and R3 is phenyl substituted with C1 to C12 linear or branched alkyl. The polymers can be cured with peroxides to yield cross-linked materials having enhanced elongation.
