Abstract
L'invention concerne un procédé pour la préparation de particules de polymère contenant un polymère de vinylarène. Ce procédé consiste à pré-polymériser ce polymère de vinylarène, laquelle matière pré-polymérisée contient également un émulsifiant; à mettre en suspension la matière pré-polymérisée et à polymériser le monomère de vinylarène dans les gouttelettes en suspension. En outre, l'invention concerne des particules de polymère comprenant un polymère de vinylarène, de l'eau et un émulsifiant, dans lequel la quantité d'eau se situe entre 8 et 15 % en poids, par rapport au poids total des particules de polymère.
