The first polyphosphazene synthesis dates from the work of Allcock published in 1964. Since then, new synthetic routes have been developed, each of them characterized by specific advantages, viz. simplification, better control over molecular weights and cross-linking processes, possibility of substitution with alkyl or aryl groups. The outstanding diversity of structures accessible through the various synthetic routes is further enhanced by the possibility of chemical modifications. This article reviews the wide range of structures and potential applications of these polymers in numerous fields. |
