  • Propellants, in particular for the propulsion of vehicles such as rockets, and process for their preparation
    Patent number: 5837930
    Abstract: Ergols, particularly for propelling missiles, containing at least one oxidant, a fuel and an energy-releasing binder. The oxidant is selected from the group which includes a nitroformate of a nitrogen compound, particularly hydrazinium or ammonium nitroformate, and a perchlorate of a nitrogen compound, particularly nitronium or ammonium perchlorate. The fuel is selected from the group which includes boron and boranes, aluminium and aluminium hydribe. The energy-releasing binder is selected from the group which includes polyglycidyl nitrate, polyglycidyl azide, polynitromethoxymethyloxetane and poly-3,3bis(azidomethyl)oxetane. Said ergols are particularly useful for propelling aerospace missiles, particularly rockets.
