Synthesis of azido polymers as potential energetic propellant binders

Composite propellants are considered as major sources of chemical energy for rocket propellants. In the preparation of composite propellant energetic formulations, the propellant binder plays a vital role. Various energetic polymeric binders were developed during last five decades to satisfy safety, high energy and processing conditions. In this review, we discuss the various synthetic routes for of preparation of high energetic polymeric binders, including glycidyl azide polymers (GAP)s, GAP co-polymers, oxetane polymers, oxirane polymers, azido polyesters, N, N′-bonded epoxy binders, aliphatic vinyl azide polymers and poly(allyl azide) (PAAz).
