| 20090170690 | NANO-LINKED METALLOCENE CATALYST COMPOSITIONS AND THEIR POLYMER PRODUCTS - The present invention provides polymerization catalyst compositions employing novel dinuclear metallocene compounds. Methods for making these new dinuclear metallocene compounds and for using such compounds in catalyst compositions for the polymerization and copolymerization of olefins are also provided. | 07-02-2009 |
| 20080287725 | Fulvene purification - The present invention provides a method of removing undesired isomers, including substituted cyclopentadiene regioisomers, from the desired fulvene in a crude fulvene composition by selectively reacting the undesired isomers with pyrrolidine and 4-(N,N-dimethylamino)benzaldehyde. This reaction converts the undesired substituted cyclopentadienes into fulvene-type compounds that is readily separated from the desired fulvene. | 11-20-2008 |
| 20080287721 | CATALYSTS FOR OLEFIN POLYMERIZATION - This invention relates to the field of olefin polymerization catalyst compositions, and methods for the polymerization and copolymerization of olefins, typically using a supported catalyst composition. In one aspect, this invention encompasses precontacting a metallocene with a borinic acid or boronic acid prior to contacting this mixture with the acidic activator-support and an organoaluminum compound. | 11-20-2008 |
