Abstract
Kaolinites, catalytically active for the polymerization of styrene, can be deactivated by treatment with 1N aqueous sodium chloride. Subsequent washing of the sodium kaolinite results in a facile hydrolysis yielding an active hydronium/aluminum kaolinite in which the exchangeable cations act as surface Br0onsted acid initiation sites.Keywords
