Abstract
For many years, DREV has been involved in the synthesis of energetic thermoplastic elastomers (ETPEs) based on linear glycidyl azide polymer (GAP). these polymers are phystically-crosslinked rubbery materials that can be melted, dissolved or recycled and could provide a new generation of binders. Since ETPEs are recyclable, disposal of the formulations at the end of their life cycle will be less problematic. Work at DREV led to the preparation of a new thermoplastic segment. The polymerization of alpha-bromomethyl-alpha-methyl-beta-propiolactone (BMMPL) or alpha-chloromethyl-alpha-methyl-beta-propiolactone (CMMPL) yielded thermoplstic homopolymers that upon azidation led to a novel energetic thermoplastic polyester: poly (alpha-azidomethyl-alpha-methyl-beta-propiolactone) (PAMMPL). An energetic copolyether-ester thermoplastic elastomer was prepared by using glycidyl azide polymer as a macroinitiator for the polymerization of BMMPL ort CMMPL. The azidation of the resulting copolyether-ester yielded an energetic thermoplastic elastomer that melted at 80-85C. Polymerization of the alpha-dibromomethyl-beta-propiolactone (DBMPL) resulted in a polymer which upon azidation yielded a new energetic polymer that can be used as a binder or into an energetic thermoplastic elastomer synthesis. This report describes mainly the synthesis and the characterization of these new ETPEs.
