Abstract

a. Procédé de préparation d'un caoutchouc synthétique pulvérulent b. Ce procédé se caractérise en ce qu'il consiste à ajouter un monomère vinylique ou un mélange de monomères vinyliques dont les polymères présentent une température de transition vitreuse supérieure à 30 degrés C, à un latex de caoutchouc synthétique, à raison de 5 à 50 parties en poids dudit monomère vinylique ou dudit mélange pour 100 parties en poids du composant de caoutchouc synthétique, et à polymériser ledit monomère dans une polymérisation radicalaire aqueuse. c. Utilisable dans l'industrie des caoutchoucs.at. Process for the preparation of a powdered synthetic rubber b. This process is characterized in that it consists in adding a vinyl monomer or a mixture of vinyl monomers whose polymers have a glass transition temperature greater than 30 degrees C, to a synthetic rubber latex, at a rate of 5 to 50 parts by weight of said vinyl monomer or said mixture per 100 parts by weight of the synthetic rubber component, and polymerizing said monomer in an aqueous radical polymerization. vs. Usable in the rubber industry.
