Abstract

Single- or multi-base propellants are produced in a solvent process from their starting components, of which at least one is moistened with alcohol, using a twin-shaft screw extruder, that has an inlet zone run at a raised temperature, then nextly a mixing and kneading zone and lastly an outlet zone. The temperature in the kneading and mixing zone and in the outlet zones is kept at a value that is higher than in the inlet zone. Furthermore there is a temperature drop towards the outlet zone.
