A process for the production of a high energy material involves reacting, in an inert organic solvent, a heterocyclic compound selected from oxirane and oxetane with a nitrogen oxide selected from dinitrogen tetroxide (N2O4) and dinitrogen pentoxide (N2O5) and, when the nitrogen oxide is N2O4, oxidising the O- nitroso substituent or substituents in the product obtained to O-nitro substituent or substituents. The heterocyclic compounds may be substitued or unsubstituted. In the former case the preferred substituents groups are halogen, alkyl, alkenyl, nitro and epoxy (as in epoxidised polybutadiene). The solvent is preferably a chlorinated alkane. |
