Abstract
Official abstract text for this publication.
The invention refers to a process for preparing a supported catalyst system for the polymerization of olefins comprising at least one active catalyst component on a support, the process comprising A) impregnating a dry porous support component with a mixture comprising at least one precatalyst, at least one cocatalyst, and a first solvent, such that the total volume of the mixture is from 0.8 to 2.0 times the total pore volume of the support component, and B) thereafter, adding a second solvent in an amount of more than 1.5 times the total pore volume of the support component. The invention refers further to a catalyst system made by this process and the use of this catalyst system for polymerization or copolymerization of olefins.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process comprising: preparing a catalyst system, wherein the preparing step comprises the steps of: A) impregnating a porous support component with a mixture comprising: (a) a precatalyst, wherein the precatalyst comprises a metallocene and an iron complex, (b) at least one cocatalyst, and (c) a first solvent to form an immobilized catalyst component, wherein the porous support component has a total pore volume from 0.1 to 10 cm 3 /g, and a re…
