ABSTRACT:
Mixed pillared clays having good thermal stabilities and high surface areas are prepared by liquid phase methods in which either (a) a discrete multi-metallic hydroxy polymer having a definite chemical formula is prepared prior to mixing with a swelling clay or (b) at least two separate metal hydroxy polymers are prepared and mixed with the swelling clay in respective amounts to satisfy selected percentages of the cationic exchange capacity of the clay.
