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 is selected from the group consisting of hydrogen and a methyl group; R.sub.2 and R.sub.3 are independently selected for each carbon atom from a group consisting of hydrogen and alkyl radical containing from 1 to 6 carbon atoms; 2.ltoreq.m.ltoreq.20; X' can additionally be selected from the group consisting of substituted and unsubstituted alkoxy, aryloxy, amino and mercapto radicals, and mixtures thereof, which are compatible with an alkoxy acrylate substituent and are known in the state of the art of polyphosphazene technology; 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.
