  • Patent number: 8268959
    Abstract: This invention describes the synthesis and use of novel energetic poly(phosphazene) materials suitable for binding high explosives. These materials may also be used as explosives in their own right. The materials possess high energy density and are highly amenable to chemical modification thereby allowing for modification to the physical properties of the material. In particular the tacky and rubbery nature of these materials makes them ideal for use as binder and co-binder materials.
