Abstract
The currently disclosed device is a novel poly(azidoaminoether)-based energetic polymer utilizing a chemical design that possesses great versatility in tailoring properties such as endothermicity, oxygen balance, flexibility, toughness, and crystallinity. Furthermore, this new chemical design will also be compatible with current polyisocyanate curing chemistry. These attributes will give such novel polymers great potential in meeting the demands of a highly energetic, yet insensitive propellant binder. This material's tailorable mechanical properties and oxygen balance as well as its backwards compatibility with current diisocyanate crosslinking methods make this novel polymer an ideal energetic binder material for use in a variety of munition systems.
