| titleOfInvention | Zirconocene isomerization process |
| abstract | In accordance with this invention it has now been found possible to selectively isomerize meso zirconocenes to racemic zirconocenes. Moreover the isomerization can be conducted using meso and racemic zirconocene mixtures whereby the resultant product is enriched in the racemic form. The process of this invention thus makes it possible to maximize, or at least materially enhance, the efficiency of racemic zirconocene production processes. Pursuant to this invention an isomerization process is provided which comprises producing a slurry of (i) a mixture of meso and racemic forms of a bridged zirconocene in (ii) a liquid ether-containing isomerization medium, and maintaining the resultant slurry at one or more temperatures at which at least a portion of the meso form of the zirconocene is isomerized to the racemic form to thereby form a racemic enriched zirconocene. |
