Abstract
Phosphazene polymers having the units ##STR1## wherein the total number of units ranges from about 3 to about 50,000, R.sub.1 and R.sub.2 are different and are C.sub.1 to C.sub.12 linear or branched alkyl, C.sub.2 to C.sub.15 linear or branched fluoroalkyl or mixtures thereof, and R.sub.3 is phenyl substituted with C.sub.1 to C.sub.12 linear or branched alkyl. The polymers can be cured with peroxides to yield cross-linked materials having enhanced elongation.
