The surface of hydrophobically-modified smectite clays (i.e., organophilic clays) are modified using a hydrophilic polymer, wherein the hydrophilic surface- modification of a hydrophobically- modified smectite clay with a hydrophilic polymer, renders the organoclays adequately dispersible in water.
L'invention concerne des argiles de type smectite à modification hydrophobe (c'est-à-dire des argiles organophiles) dont la surface est modifiée à l'aide d'un polymère hydrophile et la modification de surface hydrophile d'une argile de type smectite à modification hydrophobe à l'aide d'un polymère hydrophile rendant les organo-argiles suffisamment dispersibles dans l'eau.
