摘要:
Polyphosphazene polymers are prepared which contain repeating units represented by the formulas: wherein X is R(OR' ) n O- in which R is alkyl containing from 1 to 20 carbon atoms, aryl, alkylaryl or arylalkyl, R' is an alkylene radical and n is an integer from 1 to70; wherein X 1 = is X or is selected from the group consisting of substituted or unsubstituted alkoxy, alkenyloxy, aryloxy, alkenylaryloxy, amino and mercapto groups and wherein 20 The polymers of the invention can be utilized to form films and may also be utilized in applications for moldings, coatings, foams and the like.
