    Abstract: Pourable, discrete, finely-divided, tack-free elastomer particles, preferably containing filler, are prepared from an aqueous elastomer emulsion comprising an elastomer dissolved in a volatile inert organic solvent having an emulsifying amount of an alkylamine or alkenylamine oxyalkylate surfactant and an aqueous suspension of a filler, which process comprises gradually adding the filler-containing aqueous elastomer emulsion into a hot aqueous precipitating bath maintained at a pH of 7 or less, and simultaneously evaporating the organic solvent to obtain a precipitate of particles in water, separating therefrom and drying to produce the said pourable filler-containing elastomer particles. The pourable particles are particularly suitable in vulcanization processes to form shaped objects.
