Polyolefin polymerization catalyst and method of production use
Patent
·
OSTI ID:5143704
This patent describes a process for the preparation of a catalyst suitable for the polymerization of an {alpha}-olefin. It comprises: forming a first component by reacting reactants comprising a magnesium dihalide, a phenol, an alkylbenzoate, and a titanium tetrahydrocarbyloxide; reacting the first component with an organoaluminum halide comprising ethylaluminum sesquichloride to produce a solid product; and then contacting the resulting solid product with an activating liquid comprising titanium tetrachloride and trichlorosilane in a confined zone under pressure of at least about 70 psi.
