CA 2230587

Organoclay compositions which comprise the reaction product of a smectite-type clay having an ion exchange capacity of at least 50 meq. wt. per 100 g. clay (active basis), and an alkoxylated quaternary ammonium compound having one or two alkoxylated chains containing 0-10 moles ethylene oxide and 3-15 moles of propylene or butylene oxide residues are useful thixotropic materials, especially for the preparation of aqueous systems.

Des compositions d'argile organique, qui comprennent le produit de réaction d'une argile de type smectite ayant une capacité d'échange d'ions d'au moins 50 mEq en poids pour 100 g d'argile (base active), et un composé d'ammonium quaternaire alcoxylé possédant une ou deux chaînes alcoxylées contenant 0-10 moles d'oxyde d'éthylène et 3-15 moles de résidus d'oxyde de propylène ou de butylène, sont utiles comme matériaux thixotropes, notamment pour la préparation de systèmes aqueux.
