Title:
PROCESS FOR PREPARING A SUPPORTED CATALYST SYSTEM FOR OLEFIN POLYMERIZATION, THE CATALYST SYSTEM AND ITS USE
Document Type and Number:
WIPO Patent Application WO/2011/147573
Kind Code:
A3
Abstract:
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.
