Cross-Linking Reactions for the Conversion of Polyphosphazenes into Useful Materials

The conversion of phosphazene high polymers to useful materials depends on the development of methods to cross-link the macromolecular chains. A number of crosslinking routes have been used including chemical, photochemical, and high-energy radiation techniques. The relationship of the cross-linking processes to electrochemical, electrooptical, elastomer, structural, membrane, surface, and biomedical properties is discussed.
