ABSTRACT:
Polyphosphazene polymers are prepared which contain units represented by the formulas: ##STR1## wherein X is --NHNHCOOR in which R is alkyl containing from 1 to 12 carbon atoms, cycloalkyl containing 3 to 12 carbon atoms or aryl; 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 for moldings, coatings and the like.
