The cation-exchange properties of bentonite and kaolinite, treated with a wide range of concentrations of a vinyl acetatemaleic acid copolymer, and an isobutylene-maleic acid co-polymer were studied. Results obtained by two different methods indicate that there is a definite clay-conditioner interaction between bentonite and these conditioner materials. Very low concentrations of conditioner caused a marked decrease in the cation-exchange capacities of bentonite suspensions. Slightly higher concentrations increased the exchange capacity for both a monovalent and a divalent cation. A further increase in concentration resulted in a second decrease in exchange capacity which persisted for all higher conditioner concentrations used.
