Catalyst composition for polymerizing alpha-olefin polymers of relatively narrow molecular weight distribution |
| abstract |
A catalyst composition for polymerizing alpha-olefins is prepared by treating a carrier containing OH groups with a liquid solution containing an excess of an organomagnesium composition with respect to the OH groups and contacting the thus-formed magnesium-containing carrier with a solution of at least one transition metal compound. Prior to contacting the magnesium-containing carrier with the transition metal compound, most of the liquid must be removed therefrom, so that it comprises not more than about 6% of the liquid. The amount of the transition metal compound is such that the molar ratio of the transition metal to magnesium in the reaction mixture is about 0.3 to about 0.9. Also disclosed is a process for polymerizing alpha-olefins in the presence of the catalyst of the invention. |
