Abstract: A catalyst system useful for polymerizing olefins is disclosed. The catalyst system includes an organometallic complex that incorporates a Group 3 to 10 transition metal and an annulated cyclopentadienyl ligand that is pi-bonded to the metal. A one-pot method for making organometallic complexes from fulvene precursors is also disclosed. Additionally, the invention includes bimetallic complexes from cyclopentazulenyl compounds and a one-pot method for making them. Molecular modeling studies reveal that organometallic complexes incorporating such annulated cyclopentadienyl ligands, when combined with an activator such as MAO, should actively polymerize olefins.

Abstract: A new synthesis of a Ziegler-Natta catalyst uses a multi-step preparation that includes treating a magnesium dialkoxide compound with two halogenating/titanating agents, the second stronger than the first, an organoaluminum preactivating agent, and a heat treatment. The catalyst may be used in the polymerization of olefins, particularly ethylene, to control the molecular weight distribution of the resulting polyolefins.

Abstract: A process of forming a bimetallic catalyst composition comprising a cocatalyst (a trialkylaluminum compound) and a catalyst precursor. The precursor comprises at least two transition metals; a metallocene complex is a source of one of said two transition metals. The precursor is produced in a single-pot process by contacting a porous carrier, in sequence, with a dialkylmagnesium compound, an aliphatic alcohol, a non-metallocene transition metal compound, a contact product of a metallocene complex and a trialkyl-aluminum compound, and methylalumoxane.

Abstract: A process for the production of an ionic transition metal catalyst in supported form than is highly productive under gas phase olefin polymerization conditions. In the process a an aluminum alkyl is added to a suitable solvent after which a neutral metallocene compound is added to the solution under stirring in a quantity that provides for a ratio of Al to transition metal of at least 25:1. To this metallocene-aluminum alkyl solution is next added an ionic compound the anionic portion of which is a non-coordinating anion under stirring until all materials are dissolve. The ionic compound is added in a quantity that provides for a ratio of NCA to transition metal of at least 1:1. Next the support particles are added to the solution and thereafter the solution is heated to at least 40° C. and held at this elevated temperature for at least 0.5 hour. Thereafter the solvent is removed and the supported catalyst is dried under vacuum.
