Abstract
This invention relates to a process for the preparation of mono- and bis(azidomethyl)oxetanes. These compounds are prepared by combining a mono- or bis-X-oxetane (wherein X is, for example, a tosylate, mesylate, halogen, etc.) with an aqueous solution of a metallic azide and a phase transfer catalyst. Mono- and bis(azidomethyl)oxetanes can be polymerized to form homopolymers and copolymers with load bearing polyether backbones and highly energetic pendant groups. Such homopolymers and copolymers of the present invention are useful as energetic binders in high-energy formulations, such as propellants, explosives, and gasifiers.
