ABSTRACT:
A process for preparing a solid catalyst for the polymerization of olefins which comprises the steps of (1) reducing titanium tetrachloride with an organoaluminum compound, (2) treating the resulting .beta.-type titanium trichloride with a complexing agent, (3) treating the solid catalyst thus obtained with an organoaluminum compound, and (4) treating the resulting solid catalyst with a complexing agent, and a solid catalyst for the polymerization of olefins prepared by the above process.
