Abstract

L'invention fournit une suspension aqueuse d'une matière minérale, par exemple du carbonate de calcium, qui est préparée au moyen d'une dispersion aqueuse améliorée de polymère (méth)acryliqe neutralisé au moyen d'un ion monovalent. L'invention concerne également un agent dispersant ainsi que l'utilisation de cette suspension minérale pour la préparation d'une charge de masse pour la préparation de papier ou pour son utilisation pour la préparation d'une sauce de couchage de papier ou pour la préparation d'une composition de revêtement.
