A B S T R A C T A process for the manufacture of a free-flowing, pulverulent rubber- filler mixture containing plasticiser oil, by combining a filler containing plasticiser oil with an aqueous emulsion of a rubber solution, and precipitat- ing and drying the mixture, wherein the plasticiser oil is adsorptively bound on the finely divided active filler in an amount of from 1 to 100 parts by weight, relative to 100 parts by weight of the filler, the premix thus obtain- ed, which continues to be free-flowing and pulverulent, and consists of filler charged with plasticiser oil, is dispersed in water in the presence of an emulsifier, the resulting dispersion is intimately mixed with an aqueous emul- sion of a synthetic rubber solution, this mixture is introduced into an aqueous precipitation bath which is at a temperature of from 40 to 95°C and contains waterglass or an acid and waterglass, and from the mixture treated in this way the rubber-filler mixture, containing plasticiser oil, is precipitated with simultaneous stripping-off of the rubber solvent, and is separated from the water and dried.
