Patent application numberDescriptionPublished
20080287621Catalysts for olefin polymerization or oligomerization - Novel iron and cobalt complexes of certain novel tricyclic ligands containing a “pyridine” ring and substituted with two imino groups are polymerization and/or oligomerization catalysts for olefins, especially ethylene. Depending on the exact structure of the ligand, and polymerization process conditions, products ranging from α-olefins to high polymers may be produced. The polymers, especially polyethylenes, are useful for films and as molding resins.11-20-2008
20090054650Novel Catalysts Useful for Catalyzing the Coupling of Arylhalides with Arylboronic Acids - The present invention relates to a new method of cross-coupling aryl moieties comprising reacting an arylhalide with an arylboronic acid in the presence of a palladium compound and a compound comprising a di-alkylphosphine moiety.02-26-2009
20090143550Copolymers of vinyl-and allylsilanes - Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands. The resulting novel polymers may be crosslinked by moisture when vinylsilane contains groups bound to silicon which are hydrolyzable. The polymers are useful for wire coating, crosslinked foams, pipes, and other uses.06-04-2009
20090148631COMPOSITIONS AND PROCESSES FOR PREPARING COLOR FILTER ELEMENTS USING ALKALI METAL FLUORIDES - The present invention provides compositions derived from a polycarboxylic acid, a polyhydroxy compound, a dye and a basic crosslinking agent. The compositions can be used to prepare cross-linked films that exhibit low solvent-swell characteristics. The cross-linked films can be used to prepare color filter elements via thermal transfer processes.06-11-2009
20090148788COMPOSITIONS AND PROCESSES FOR PREPARING COLOR FILTER ELEMENTS - Provided are compositions derived from a polycarboxylic acid, a copper phthalocyanine complex, and a plasticizer. The compositions can be used to prepare color filter films that exhibit lower lip heights, suitable in color filter elements, for example, in liquid crystal display devices.06-11-2009
20090149325COMPOSITIONS AND PROCESSES FOR PREPARING COLOR FILTER ELEMENTS USING ALKALI METAL CARBOXYLATES - The present invention provides compositions derived from a polycarboxylic acid, a polyhydroxy compound, a dye and a basic crosslinking agent. The compositions can be used to prepare cross-linked films that exhibit low solvent-swell characteristics. The cross-linked films can be used to prepare color filter elements via thermal transfer processes.06-11-2009
20090149326COMPOSITIONS AND PROCESSES FOR PREPARING COLOR FILTER ELEMENTS USING VANADIUM CATALYSTS - Provided are compositions derived from a polycarboxylic acid, a polyhydroxy compound, a dye and a vanadium catalyst. The compositions can be used to prepare films that can be used to prepare color filter elements via thermal transfer processes.06-11-2009
20090162693TETRA-SUBSTITUTED CHRYSENES FOR LUMINESCENT APPLICATIONS - This invention relates to electroluminescent 3,6,9,12-tetrasubstituted chrysenes that are useful in electroluminescent applications. It also relates to electronic devices in which the active layer includes such a chrysene composition.06-25-2009
20090275723PROCESSES FOR MAKING STABILIZED DIVALENT GERMANIUM AND TIN COMPOUNDS - Processes for making ivalent germanium and tin compounds are provided. The divalent germanium and tin compounds have been found to be efficient catalysts for the formation of polyurethanes.11-05-2009
20100112237THERMAL TRANSFER DONOR ELEMENTS WITH IONIC LIQUIDS - Disclosed herein are compositions derived from a polycarboxylic acid, and an ionic liquid. The compositions can be used to prepare thermal transfer donor elements.05-06-2010
20110151152THERMAL TRANSFER DONOR ELEMENTS WITH WATER SOLUBLE BLUE DYES - Provided are compositions derived from a polycarboxylic acid, water soluble blue dyes and blue pigments in a fixed weight ratio. The compositions can be used to prepare thermal transfer donor elements that can be used to make blue pixels of a color filter element with improved surface characteristics and lightfastness.06-23-2011
