Abstract
Elastomeric particles, which have a tendency to agglomerate, are rendered non-agglomerating by contacting those particles with an aqueous solution or dispersion of a polyurethane rubber, a high Mooney viscosity, high gel content rubber and/or a soap, and optionally a polar binder, separating the coated elastomeric particles from the solution or dispersion, and then drying the elastomeric particles while keeping the coated particles in motion.
