| titleOfInvention |
Synthesis of polymerization catalyst components |
| abstract |
The present invention provides a method of synthesizing fluorided metallocene catalyst components comprising contacting at least one fluoriding agent comprising fluorine with one or more alkylated metallocene catalyst components comprising one or more non-halogen leaving groups to produce a fluorided catalyst component; wherein from less than 3 equivalents of fluorine are contacted for every equivalent of leaving group. The method of the invention is exemplified by the following reaction which takes place in a non-coordinating diluent such as pentane, wherein one or both of the "Cp" rings may be substituted with an R group as described herein, and may be bridged. The reaction can be run at any desirable temperature, desirably between 10 DEG C and 35 DEG C. The reaction product of the BF3 and dimethyl zirconocene is the fluorided zirconocene. The mole ratio of the BF3 fluoriding agent and the starting metallocene is less than 2:1 (fluoriding agent:metallocene) in one embodiment, and less than or equal to 1.6:1 in a particular embodiment, and less than or equal to 1.5:1 in a more particular embodiment, and less than or equal to 1.2:1 in yet a more particular embodiment. |
