Catalyst for the manufacture of polyethylene with a narrow molecular weight distribution |
| abstract |
An ethylene-alpha-olefin copolymerization catalyst is prepared by impregnating a porous support, such as silica, with a contact mixture of an organomagnesium compound such as dialkyl magnesium and a silane compound which is free of hydroxyl groups, such as tetraethyl orthosilicate. A transition metal component such as titanium tetrachloride is then incorporated into the support in a specific ratio to the magnesium and silane components. Activation of this catalyst precursor with a trialkylaluminum compound results in a catalyst system which is effective for the production of ethylene copolymers. |
