A method for sulfonating aminophosphazenes with the use of 1,3-propanesultone is described. The alkanesulfonation reactions were first developed with small molecule phosphazene cyclic trimers as models for high polymeric phosphazenes. High molecular weight poly(aminophosphazenes) were then sulfonated using similar techniques. The structure and properties of the alkanesulfonated polymers were examined by DSC, intrinsic viscosity, and 31P, 13C, and 1H NMR spectroscopy. This synthetic approach to sulfonated polymers is valuable for the development of new biomedical materials, membranes, reversibly cross-linkable polymers, surfactants, and polyelectrolytes.
