A process for preparing barrier polymer compositions comprises adding an additive, in the form of a latex, to an aqueous dispersion of barrier polymer particles, coagulating the latex additive on the surface of the polymer particles to coat the polymer particles and then drying the latex-coated polymer particles.
Un procédé de préparation de compositions de polymères formant barrière consiste à ajouter un additif, se présentant sous la forme d'un latex, à une dispersion aqueuse de particules polymères formant barrière, à coaguler l'additif au latex sur la surface des particules polymères afin d'enrober les particules polymères et ensuite à sécher les particules polymères enrobées de latex.
