Olefin polymerization catalyst |
| abstract |
In a method to produce an alpha-olefin polymerization catalyst comprising reducing titanium tetrachloride with an aluminum alkyl, contacting the resulting reduced solid with a pretreatment amount of alpha-olefin monomer under polymerization conditions and reacting the resulting product with a Lewis base complexing agent and additional titanium tetrachloride, the improvement comprising reacting the Lewis base complexing agent in a molar ratio to the reduced titanium compound of greater than 1.15 to 1. |
