ABSTRACT:
Polyphosphazene polymers are prepared which contain repeating units represented by the formulas: ##STR1## wherein X is represented by ##STR2## wherein R.sub.1 and R.sub.2 are independently selected from a group consisting of substituted or unsubstituted aliphatic, aryl, araryl, alkylaryl and heterocyclic radicals or R.sub.1 and R.sub.2 can be linked to form a cyclic radical and R.sub.3 is an aliphatic hydrocarbon radical or hydrogen, X' is a substituted or unsubstituted alkoxy, aryloxy, amino or mercapto substituent group or mixtures thereof which are compatible with an N-substituted amino substituent and are known in the state of the art of polyphosphazene technology; and 20.ltoreq.(w+y+z).ltoreq.50,000 per polymer and (y+z)>0.
The polymers of the invention can be utilized to form protective films and can also be utilized in applications such as molding, coatings, foams and the like.
