The present invention provides an olefin polymerization pro-catalyst that includes at least one multidentate ligand. The pro-catalyst includes a Group 3 to 10 transition or lanthanide metal and one or more anionic or neutral ligands in an amount that satisfies the valency of the metal such that the pro- catalyst has a net zero charge. The present invention also discloses a method for making the pro-catalyst.
La présente invention porte sur un pro-catalyseur de polymérisation oléfinique qui comprend au moins un coordinat multicoordinant. Le pro-catalyseur comprend un métal de transition ou lanthanide du groupe 3 à 10 et un ou plusieurs ligands anioniques ou neutres dans une quantité satisfaisant à la valence du métal de sorte que le pro-catalyseur ait une charge nulle nette. Cette invention porte également sur un procédé de fabrication du pro-catalyseur.
