Abstract
A process is disclosed for pillaring layered materials which do not swell appreciably in water. The process comprises first intercalating an amine or other neutral molecule such as an amide or dimethyl sulfoxide between the layers of the material to be pillared. This allows the subsequent incorporation of inorganic pillars which are more temperature stable than the intercalated amine.
