Abstract: New ligands, compositions, metal-ligand complexes and arrays with pyridyl-amine ligands are disclosed that catalyze the polymerization of monomers into polymers. Certain of these catalysts with hafnium metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, isobutylene or styrene. Certain of the catalysts are particularly effective at polymerizing propylene to high molecular weight isotactic polypropylene in a solution process at a variety of polymerization conditions.

Abstract: The present invention relates, inter alia, to methodologies for the synthesis, screening and characterization of organometallic compounds and catalysts (e.g., homogeneous catalysts). The methods of the present invention provide for the combinatorial synthesis, screening and characterization of libraries of supported and unsupported organometallic compounds and catalysts (e.g., homogeneous catalysts). The methods of the present invention can be applied to the preparation and screening of large numbers of organometallic compounds which can be used not only as catalysts (e.g., homogeneous catalysts), but also as additives and therapeutic agents.

Abstract: The inventions disclosed herein are new complexes and catalysts comprising metal-ligand complexes or compositions of metal precursors and ligands (and optionally activators) that catalyze polymerization and copolymerization reactions, particularly with monomers that are olefins, diolefins or acetylenically unsaturated. These compositions can also polymerize monomers that have polar functionalities in homopolymerizations or copolymerizations. Also, diolefins in combination with ethylene or &agr;-olefins or 1,1-disubstituted olefins may be co-polymerized. The new catalyst compositions can be prepared by combining a metal precursor with a suitable ligand and, optionally, an activator or combination of activators. The main feature of this invention is the use of new metal ligand complexes to provide the active polymerization catalysts.

Abstract: The present invention relates to a process of conducting research using combinatorial techniques wherein metal-ligand compositions are synthesized and screened for reactivity in reactions of interest, particularly metal-ligand compounds which are suitable for use as catalysts. In the process, an array of different metal-ligand compositions is prepared by delivering a dissolved, soluble metal precursor and a metal-binding ligand to each reaction vessel or well in the array, where they may optionally be combined with an activator and/or other additives. The resulting metal-ligand composition in each vessel is then screened for reactivity in a chemical reaction of interest, particularly for catalytic activity in a polymerization reaction.

Abstract: Erbium metal catalysts, compositions, metal-ligand complexes and arrays catalyze the polymerization of monomers, particularly olefins, into polymers. These have shown particularly good activity and can be screened in a high throughput manner using arrays of these catalysts, compositions and metal-ligand complexes.

Abstract: Ionic liquids function as the initiator or as a co-solvent for the production of very high molecular weight polyisobutylenes, e.g., having a weight-average molecular weight over 100,000. These ionic liquids may be characterized by the general formula A+B− where A+ represents any stable inorganic or organic cation and B− represents any stable organic or inorganic anion.

Abstract: Processes for the polymerization of monomers, particularly olefins, into polymers use erbium compositions, metal-ligand complexes and compositions. The processes proceed with good conversion in a number of different methods.

Abstract: The present invention discloses methods and materials for constructing combinatorial libraries composed of organometallic compounds immobilized on solid supports and encoded with detectable tags. The encoded library of organometallic compounds is especially useful for rapidly screening large numbers of member compounds for catalytic performance. These immobilized catalysts can be pooled in a single reactor where they are screened for a predefined property, such as catalytic activity and selectivity.

Abstract: A parallel reactor system including a reactor and vessels in the reactor for holding reaction mixtures, and a cannula for introducing fluid reaction material into the vessels. A robot system is operable to insert the cannula into cannula passages in the reactor for delivery of reaction materials, including slurries, to respective vessels, and to withdraw the cannula from the cannula passages after delivery. Related methods are also disclosed.

Abstract: Novel compositions and metal compounds having an ancillary ligand structure polymerize monomers and functionalized monomers, either alone or in the presence of an activator. The ancillary ligand structure is a chelating ligand that may optionally be further bound to the metal via a dative or covalent bond.
