摘要：

Various polymers were exposed to atomic oxygen O(3P) and comparisons made of their stability. The rates of reaction and mass removal for polyphosphazenes exposed to atomic oxygen were found to be significantly lower than for other polymers evaluated in this study. Surface analysis of poly‐phosphazene films indicated that O(3P) induces rearrangements in the phosphorus‐nitrogen backbone of the polymer resulting in crosslinking and cleavage of some pendant groups that are then replaced by oxygen.
