Abstract

A process for the production of a free flowing filled elastomer powder by combining an elastomer latex with a filler suspension is disclosed wherein the combining of elastomer latex and filler suspension takes place in the presence of about 0.1-15 parts by weight--calculated per 100 parts by weight of elastomer solid in the elastomer latex--of a high-molecular-weight amine with quaternary nitrogen functions and with an average molecular weight of about 10.sup.4 to 10.sup.8.
