Abstract (en)
[origin: WO02083751A1] An olefin polymerization catalyst component is prepared by making a solution of a transition metal complex of a selected tridentate ligand, adsorbing the complex onto a silica or silica-alumina support, and separating the solution from the supported transition metal complex component, which is storage stable. Olefin polymerizations with this component may be carried out with high catalyst productivity using cocatalysts such as trialkylaluminum compounds.
