    摘要： Free-flowing rubber powders containing particles of a diene, acrylate or EPDM rubber having an average diameter of from 0.01 to 10 mm which contain, polymerized thereon, a shell of the polymer or copolymer of one or more vinyl monomers in a quantity of from 2 to 20% by weight, based on the rubber, and a process for their production, wherein a latex of a diene, acrylate or an EPDM rubber having a glass transition temperature of below 0.degree. C. is completely broken with the formation of an aqueous suspension of the rubber, from 2 to 20% by weight, based on the rubber, of one or more vinyl monomers which form polymers having glass transition temperatures of above 25.degree. C. are then introduced into the suspension and the monomer(s) is/are polymerized, optionally after adding radical-forming catalysts.
