摘要
Polymerization of -bromomethyl--methyl--propiolactone (BMMPL) or -chloromethyl--methyl--propiolactone (CMMPL) yielded thermoplastic homopolymers that upon azidation led to a novel energetic thermoplastic polyester: poly(-azidomethyl--methyl--propiolactone) (PAMMPL). An energetic copolyether-ester thermoplastic elastomer was prepared by using glycidyl azide polymer, a dihydroxyl terminated energetic polymer, as a macroinitiator for the polymerization of BMMPL or CMMPL. The azidation of the resulting copolyether-ester yielded an energetic thermoplastic elastomer that melted at between 80 C. and 85 C. Polymerization of -dibromomethyl--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.
