ABSTRACT:
Polyphosphazene polymers are prepared which contain units represented by the formulas: ##STR1## wherein X is ##STR2## in which R is alkylene radical containing from 0 to 10 carbon atoms, R' is hydrogen or alkyl containing from 1 to 10 carbon atoms and n is an integer of from 0 to 10; wherein X' is X or is selected from the group consisting of substituted or unsubstituted alkoxy, aryloxy, 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 such as moldings, coatings, foams and the like.
