Abstract
High density solid propellants are prepared by a process which comprises mixing the solid propellant components comprising a perfluorinated polymer, such as high molecular weight polytetrafluorethylene, and an inorganic oxidizer salt, such as NF.sub.4 BF.sub.4, with a dispersion containing a dissolved low molecular weight perfluorinated polymer, a suspended low molecular weight pefluorinated polymer and a suitable solvent, removing the solvent from the mixture, and drying the solids.

A process for preparing a high density solid propellant which comprises mixing the solid propellant components which comprise a high molecular weight perfluorinated polymer binder and an inorganic oxidizer salt with a dispersion comprising a dissolved low molecular weight perfluorinated polymer, a suspended low molecular weight perfluorinated polymer and a suitable solvent;
- removing the solvent;
- and drying the resulting solids.
A high density solid propellant consisting essentially of 25 to 70% of NF.sub.4 BF.sub.4, 5 to 50% of a polytetrafluoroethylene having an average molecular weight of about 3 million and 10 to 25 percent of a polytetrafluoroethylene having an average molecular weight of about 3700.
