ABSTRACT:
Polyphosphazene polymers are prepared which contain repeating units represented by the formulas: ##STR1## wherein X and X' are the same or different and are represented by: ##STR2## wherein R.sub.1-4 are independently selected from the group consisting of hydrogen, halogen, nitro, cyano, alkylmercapto, arylmercapto, dialkylamine, alkyl, aryl, alkoxy, aryloxy and heterocyclic radicals or R.sub.1 and R.sub.3 when taken together can form a cycloalkyl or heterocyclic ring; X' can also be selected from a group consisting of chloro radicals, substituted or unsubstituted alkoxy, aryloxy, amino and mercapto radicals or mixtures thereof; and 20.ltoreq.(w+y+z).ltoreq.50,000 per polymer.
The polymers of the invention can be utilized to form protective films and can also be utilized in applications such as for molding, coatings, foams and the like.
