| titleOfInvention | Cocatalyst for vanadium-containing ethylene polymerization catalyst |
| abstract | The present invention is directed to a novel halosilane cocatalyst component which may be used in conjunction with an aluminum-containing cocatalyst to provide enhanced catalytic activity of a vanadium based solid catalyst component in the polymerization of alpha -olefins. In addition to the enhancement in the catalytic activity obtaining using the present catalyst system, the resultant polymer produced by the present invention exhibits improved physical properties compared with polymers produced by prior art vanadium based catalyst systems. Thus, the catalyst system of the instant invention represents an advance in the art in view of the combination of increased catalytic activity, i.e. yield of polymer produced, and enhanced physical properties of the polyolefin produced. In accordance with the present invention, a catalyst system is provided which comprises a solid catalyst component and a halosilane cocatalyst component. The solid catalyst component of the present invention is the product formed by admixing a solid inorganic oxide, an organometallic compound, a vanadium-containing compound and an organic reagent. In another aspect of the present invention, a process of the polymerization of alpha -olefins is disclosed. In this process at least one olefin is polymerized under olefin polymerization catalyst utilizing the catalyst system of the present invention, which includes the solid catalyst component of the present invention, and a cocatalyst selected from the group consisting of halosilane compounds and admixtures thereof with aluminum compounds. |
