Polyphosphazene polymers are prepared which contain repeating units represented by the formulas:
wherein X is represented by:
wherein Y is selected from the group consisting of
and-SO2-and p = 0 or 1; when p = 0, R1 and R2 are independently selected from a group consisting of substituted or unsubstituted aliphatic, aryl, araryl, and alkylaryl radicals or R, and R2 can form a cyclic amide containing radical wherein R1, and R2 taken together are selected from a group consisting of (CH2)n where n = 2 to 12, wherein R3 is a lower alkyl radical or hydrogen; and when p = 1, R and R2 taken together form a linkage in a cyclic imide containing radical selected from a group consisting of (CH2)n, where n' = 2 or 3 and
where R3 is as defined above, R4 is selected from the group consisting of hydrogen, halogen and alkyl radical containing 1 to 6 carbon atoms; and p' is 0 to 4, X' is a substituted or unsubstituted alkoxy, aryloxy, amino or mercapto substituent group or mixtures thereof which are compatible with an N-substituted amido substituent and are known in the state of the art of polyphosphazene technology; and 20≤(w + y + z)≤ 50,000 per polymer and (y + z) > 0.
The polymers of the invention can be utilized to form pro- tectivefilms and can also be utilized in applications such as for molding, coatings, foams and the like.
