Abstract:
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.
