MULTIPLE SITE OLEFIN POLYMERIZATION CATALYSTS AND METHODS |
摘要 |
MULTIPLE SITE OLEFIN POLYMERIZATION CATALYSTS AND METHODS A multiple site solid catalyst component capable of producing polyolefins having a broad or multimodal molecular weight distribution, such as a bi-modal molecular weight distribution, is prepared by contacting a particulate solid support with a zirconium compound or complex to bind the zirconium compound or complex to the support, optionally followed by contacting the supported zirconium compound or complex with a Lewis acid and washing an intermediate product, optionally isolating and washing the supported zirconium compound or complex or resulting intermediate product to remove soluble by-products therefrom, and reacting the washed or unwashed supported zirconium compound or complex or intermediate product with a titanium or vanadium compound to produce a solid catalyst component.
