ABSTRACT:
Polyphosphazene polymers are prepared which contain randomly distributed units represented by the formulas: ##STR1## wherein X is selected from the group consisting of substituted and unsubstituted mono, di, and tri nitro substituted phenoxy groups and mixtures thereof and wherein X' is the same as X or is selected from the group consisting of substituted and unsubstituted alkoxy, alkenyloxy, aryloxy, alkenylaryloxy, amino and mercapto groups.
The polymers of the invention can be utilized to form protective films and may also be utilized in application such as for moldings, coatings, and the like where heat stability and solvent resistance are important.
