Method for producing an aqueous dispersion of particles that are made up of polymers and inorganic solid matter which consists of fine particles

   
   

A process for preparing an aqueous dispersion of particles composed of addition polymer and finely divided inorganic solid (composite particles), in which process a mixture of ethylenically unsaturated monomers is dispersely distributed in aqueous medium and is polymerized by the method of free-radical aqueous emulsion polymerization by means of at least one free-radical polymerization initiator in the presence of at least one dispersely distributed, finely divided inorganic solid and at least one dispersant.

Un procédé pour préparer une dispersion aqueuse des particules composées de polymère d'addition et de solide inorganique finement divisé (particules composées), dans lequel le processus un mélange des monomères éthyléniquement insaturés est dispersely distribué dans le milieu aqueux et est polymérisé par la méthode de polymérisation aqueuse libre-radicale d'émulsion au moyen d'au moins un initiateur libre-radical de polymérisation en présence au moins d'un dispersely distribué, a finement divisé plein inorganique et au moins un dispersant.
