Nitrocellulose (NC) is a high-energetic polymer with good physicochem. properties and it can be processed to different shapes (flakes, cylinders, spherical balls). NC granules are used for solid rocket propellants (homogeneous propellants) or gun ammunition (spherical powders). NC granules were obtained by water method in laboratory scale - its safe method for the production of spherical powder, because NC was suspended in water. The used NC was characterized by different viscosity and nitrogen content in the range of 12.2-13.3%. Other process components were: Et acetate as solvent, centralite I as stabilizer, starch as protective colloid, sodium sulfate as dehydrating agent. Physicochem. properties of obtained granules were examined, e.g. thermal properties, d., heat of combustion. The influence of nitrogen content on the properties of obtained NC granules was determined in this work.
