ABSTRACT:
Polyphosphazene polymers are prepared which contain repeating units represented by the formulas: ##STR1## wherein X is R(OR').sub.n O-- in which R is alkyl containing from 1 to 20 carbon atoms, aryl, alkylaryl or arylalkyl, R' is an alkylene radical and n is an integer from 1 to 70; wherein X' is X or is selected from the group consisting of substituted or unsubstituted alkoxy, alkenyloxy, aryloxy, alkenylaryloxy, amino and mercapto groups and wherein 20.ltoreq.(a+b+c).ltoreq.50,000 per polymer.
The polymers of the invention can be utilized to form films and may also be utilized in applications for moldings, coatings, foams and the like.
