Zusammenfassung:	Pourable elastomer-filler mixtures, optionally containing plasticizer oil, are prepared by an improved process, the process comprising mixing an aqueous emulsion of an elastomer solution with an aqueous dispersion of a filler(s); introducing this mixture into water containing a precipitant(s); precipitating the elastomer-filler mixture while simultaneously removing the elastomer solvent by distillation; separating the thus-precipitated elastomer-filler mixture from the water; and drying the elastomer mixture under constant agitation; and the improvement comprising:
