The invention relates to a method for producing an aqueous dispersion of particles (composite particles) that are made up of polymers and inorganic solid matter which consist of fine particles. A mixture of ethylenically unsaturated monomers is dispersely distributed in an aqueous medium and is polymerised according to the method of the radical aqueous emulsion polymerisation in the presence of at least one dispersely distributed inorganic solid matter which consists of fine particles and at least one dispersing means using at least one radical polymerisation initiator.
L'invention concerne un procédé de production d'une dispersion aqueuse de particules (particules composites) constituées d'un polymérisat et d'un solide anorganique en fines particules. Selon ledit procédé on procède à la dispersion, dans un milieu aqueux, d'un mélange de monomères éthyléniquement insaturés et, au moyen d'au moins un initiateur de polymérisation radicalaire et en présence d'au moins un solide organique en fines particules dispersé et d'au moins un dispersant, ledit mélange est soumis à une polymérisation selon le procédé de la polymérisation en émulsion aqueuse radicalaire.
