Abstract

Process for the manufacture of a propellant for base-bleed gas generators, thus for generators made of a gas-producing charge for the increase of range wherein a binder and one or more granular or powdery solid substances are used at least one of which is an oxidant, characterized thereby that the binder is a thermoplastically deformable elastomer, that solvents are added to said elastomer which is thoroughly mixed with the solid substance and that said elastomer is deposited thereon by removal of the solvent with the formation of a granulate.
