ABSTRACT:
Polyphosphazene polymers are prepared which contain repeating units represented by the formulas: ##STR1## wherein X is the same or a mixture of different radicals represented by the following structural formula: ##STR2## wherein R.sub.1 is selected from the group consisting of alkyl and aryl radicals and R.sub.2, R.sub.3 and R.sub.4 are independently selected from the group consisting of hydrogen, alkyl, alkenyl aryl, alkoxy, aryloxy and heterocyclic radical and R.sub.1-4 can be substituted with one or more substituents which are non-reactive with various materials during polymer formation; and X' can be substituted or unsubstituted and is selected from the group consisting of halogen, alkoxy, aryloxy, amino and mercapto radicals or mixtures thereof; and 20 (w+y+z) 50,000 per polymer.
The polymers of the present invention can be utilized in applications such as molding, coatings, foams, fibers and the like.
