Abstract: Polyphosphazene copolymers are prepared which contain randomly distributed units represented by the formulas: ##STR1## wherein X is --CNO.sub.2 R.sub.1 R.sub.2 in which R.sub.1 and R.sub.2 are H, a branched, straight chain or cyclic alkyl group containing from 1 to 12 carbon atoms or mixtures thereof, and wherein X' is selected from the group consisting of substituted and unsubstituted alkoxy, alkenyloxy, aryloxy, alkenylaryloxy, amino and mercapto groups or mixtures thereof. In the copolymer units represented by the above formulas, all X substituent groups may be the same or they may be mixed and all X' substituent groups may be the same or mixed. In the mixtures, the X substituent groups may be mixtures of different --CNO.sub.2 R.sub.1 R.sub.2 groups and the X' substituent groups may be mixtures of alkoxy, alkenyloxy, aryloxy, alkenylaryloxy, amino and mercapto groups. The copolymers of the invention can be utilized to form protective films and may also be utilized in applications such as for moldings, coatings, and the like.
