Abstract
An energetic copolyurethane thermoplastic elastomer is prepared by polymerizing a dihydroxyl terminated telechelic energetic polymer having a functionality of two or less with a diisocyanate at a NCO/OH ratio of about 0.7 to 1.2. The resulting copolymer is easy to incorporate in gun propellant formulations and is recyclable.
