Polyphosphazene polymers are prepared which contain repeating units represented by the formulas: <CHEM> wherein X is R(OR min )nO- in which R is alkyl containing from 1 to 20 carbon atoms, aryl, alkylaryl or arylalkyl, R min is an alkylene radical and n is an integer from 1 to 70; wherein x1 = is X or is selected from the group consisting of substituted or unsubstituted alkoxy, alkenyloxy, aryloxy, alkenylaryloxy, amino and mercapto groups and wherein 20 < (a + b + c) < 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.
