ABSTRACT:
Polyphosphazene copolymers are prepared by a novel, simplified process which contain novel, randomly distributed units represented by the formulas: ##STR1## wherein X is --OSi(OR).sub.3 in which R is a branched, straight chain or cyclic alkyl group containing from 1 to 12 carbon atoms and mixtures thereof and wherein X' is selected from the group consisting of substituted and unsubstituted alkoxy, aryloxy, amino and mercapto groups. The alkyl groups may vary in carbon chain length or structure within the silicate or all be the same.
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. The copolymers of this invention also crosslink at room temperature in the presence of water.
