ABSTRACT:
Polyphosphazene polymers are prepared which contain repeating units represented by the formulas: ##STR1## wherein X is represented by one or more of the following structural formulas: ##STR2## wherein R.sub.1-11 are independently selected from the group consisting of hydrogen, halogen, cyano, nitro, and substituted and unsubstituted alkyl, aryl, alkoxy, aryloxy, alkylmercapto, and dialkylamino radicals, and R.sub.1 or 3 and R.sub.2, or R.sub.5 and R.sub.6 taken together can form a substituted or unsubstituted benzene ring structure; X' can represent one or more substituents from the group consisting of a halogen radical, substituted and unsubstituted alkoxy, aryloxy, amino and mercapto radicals which are known in the state of the art in poly(phosphazene) technology and which are compatible with the copolymer substituents. The polymer can contain from 20 to 50,000 of such units such that 20.ltoreq.(w+y+z).ltoreq.50,000.
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.
