Patent abstract
A two-step catalyst preparation method is disclosed. First, a support is combined with an indenoindolyl Group 3-10 metal complex and a first activator comprising an alkyl alumoxane to give a supported complex. The supported complex is subsequently combined with a second activator comprising an ionic borate to produce a borate-treated supported complex. Activating indenoindolyl metal complexes in this sequence surprisingly provides an exceptional activity boost compared with other ways of activating them with either or both types of activators.
