Abstract
A process and catalyst for the polymerization of olefins wherein the catalyst comprises the product obtained by reacting a complex of a magnesium dihalide and a tetraalkyl titanate with the product resulting from a reaction between an organometallic compound and a hydroxyl-containing carrier such as silica and then reacting that product with a titanium halide.
Claims10
A method for producing a catalyst comprising
- (1) reacting a first component comprising the product of a reaction between a magnesium dihalide and a tetraalkyl titanate with a second component comprising the product of a reaction between a substantially anhydrous particulate hydroxyl-containing refractory carrier and an organometal compound of a metal of Group I to V and then
- (2) reacting the resulting solid with titanium tetrahalide.
