Abstract
A method of producing an energetic polymer comprises reacting at least one energetic diol with at least one of a diacid halide and a diacid halide derivative to produce a geminal dinitro polyester. A method of producing an energetic binder, and a method of producing an energetic composition are also described.
Claims22
A method of producing an energetic polymer, comprising:
- combining, under a nitrogen gas atmosphere, a mixture consisting of a diacid chloride and an organic solvent with a solution consisting of an amine and the organic solvent to react the diacid chloride with the amine and form an acyl ammonium salt;
- and
- reacting 2,2-dinitro-1,3-propanediol with the acyl ammonium salt to produce a geminal dinitro polyester.
A method of producing an energetic binder, comprising:
- combining, under a nitrogen gas atmosphere, a mixture consisting of a diacid chloride and an organic solvent with a solution consisting of an amine and the organic solvent to react the diacid chloride with the amine and form an acyl ammonium salt;
- and
- reacting 2,2-dinitro-1,3-propanediol with the acyl ammonium salt to produce a geminal dinitro polyester;
- and
- crosslinking polymer chains of the geminal dinitro polyester.
