Abstract: Process for preparing polymer powder from an aqueous polymer dispersion with water-soluble compounds, the fraction of such compounds being smaller than that of said aqueous polymer dispersion and being based on the polymer present in the form of polymer particles insoluble in water, which comprises subjecting the aqueous polymer dispersion to membrane filtration in a first step of the process and to spray drying in a subsequent second step of the process.

Abstract: Método para la preparación de polvos poliméricos, a partir de una dispersión polimérica acuosa, con una fracción más pequeña de compuestos solubles en agua en comparación con esta dispersión polimérica acuosa, referida al polímero presente en forma de partículas poliméricas insolubles en agua, caracterizado porque la dispersión polimérica acuosa se somete en un primer paso de proceso a una filtración de membrana y en un segundo paso de proceso a un secamiento por aspersión.
