Dies 1st gegeben bei einem Stickstoff-According to the invention, a porous one is used instead of the conventional one Granules used. The porosity can vary in the manufacture of the Granulate »as.B. duroh incorporation of water-soluble salts and later dissolving of the same, as well as by the fineness and quantity of these salts can be achieved in the following way. A nitrocellulose with 13p1 pounds of nitrogen, stabilizers and the desired additives mixed and in a kneader with additive of 110 56 Kocheais gelatinized with the help of an ether-alcohol mixture. The mass obtained is pressed through a die with a diameter of 1.8 mm and cut to a length of 1.8 mm. To remove the solvent, the granulate is soaked in water at 40-65 ° C. for about 40 hours and then air-dried. So that the porosity obtained in this way is retained during the subsequent gelatinization, it is necessary - as naoh Another feature of the present invention was found • ine. use such nitrocellulose as specified in the.
