Abstract
A carboxylated phosphazene polymer, comprising a phosphazene polymer backbone covalently coupled to a carboxylate-containing compound through a divalent organic radical attached at one end to the carboxylate by an amide bond formed at a primary aliphatic amino group of the radical and at the other end to a phosphorous of the phosphazene backbone.
