Abstract
Catalysts for olefin polymerization which consist essentially of a transition metal compound, a modified clay compound and an organic aluminum compound, wherein the modified clay compound comprises a reaction product of a clay mineral and a proton acid salt of a specific amine compound, as well as a method of polymerizing olefins using such catalysts. It is possible thereby to obtain olefin polymers with high productivity and low ash content.
