Abstract
The invention relates to a process for the drying of coagulated water-containing rubber particles. These are treated with an aqueous solution of any desired substances in monodisperse solution in water in such a way that, at least for some period, the surface of the rubber particles is completely covered by the aqueous solution. It is preferable to use an aqueous solution of substances selected from the group consisting of salts, alcohols, acids and sugars. This method can reduce the internal water content between the particles resulting from coagulation, without major usage of energy or time.
