Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a compound that comprises a pseudolaminar silicate of natural origin, which is at least one clay of the paligorskite-sepiolite group, characterized in that said method comprises the following steps: defibrillating the microfibre bundles of the at least one clay in water; dispersing the defibrillated clay in an organic or inorganic liquid solvent until a stable gel is formed; adding to the dispersion at least one clay-surface-modifying agent; removing the solvent from the dispersion by means of a solid-liquid separation process and/or drying process; and deagglomerating the final compound until a powdered product is obtained. A further object of the present invention is the compound that can be obtained using said method, as well as the use of the compound as an additive or filler in composite polymeric materials in order to enhance the properties thereof, the composite polymeric material likewise being encompassed within the present invention.
