Finely divided, pulverulent rubbers containing filler which contain further processing and vulcanization auxiliaries necessary for the production of vulcanizable rubber mixtures, which rubbers are pourable even after exposure to mechanical action, and to a process for the production thereof. The rubber powder is obtained within two precipitation steps. These rubber powders are used for the production of vulcanizable rubber mixtures. The fillers used, which comprise not only precipitated silicas but also carbon blacks known in the rubber industry, are optionally surface modified with organosilicon compounds.
