ABSTRACT:
A method for the alkylsulfonation of polymeric and cyclic trimer phosphazenes that includes reacting the phosphazene with a sultone. This method can be used to prepare sulfonated phosphazenes that are useful as biomedical materials, membranes, reversibly cross-linkable polymers, surfactants, and polyelectrolytes.
