ABSTRACT:
A process for modification, in particular for surface modification of an organophilic clay material, encompassing the following steps:a) provision of a dry, pulverulent, organophilic clay material (component a);b) provision of at least one additive (component b) for modification of component a);c) intensive mixing of components a) and b) in a high-shear mixing assembly,where no water or solvent is added or used for addition of component b).
