Polyolefin polymerization process and catalyst.

摘要

A catalyst and process for polymerizing olefins wherein the catalyst comprises a titanium-containing component prepared by reacting a magnesium dihalide, 4-phenyl phenol, ethyl benzoate, and titanium tetrabutoxide, and an organoaluminum halide and then reacting that product with a mixture of TiCl<Sub>4</Sub>, HSiCl<Sub>3</Sub>, and SiCl<Sub>4</Sub>.
