ABSTRACT:
A process whereby a smectite clay having a cationic exchange capacity of at least 50 meq./100 gm of clay is reacted with a quaternary ammonium compound to yield a cationic structure suitable as a thickener for aqueous suspensions, particularly latex paints and caulks. The general structure of the quaternary ammonium compound is typically a nitrogen atom bonded to four separated carbon chains where one chain can be a methyl or alkyl group containing 10 to 22 carbons, and the second chain an alkyl group containing from 10 to 22 carbons or a polyoxyethylene chain. The third and fourth chains are polyoxyethylene chains where the total munber of ethylene oxide units is from 5 to 200 moles.
