摘要： A method for making single-site catalysts useful for olefin polymerization is disclosed. A nitrogen-functional heterocycle is first deprotonated with an alkyllithium compound, followed by reaction of this anionic ligand precursor with about 0.5 equivalents of a Group 4 transition metal tetrahalide in a hydrocarbon solvent at a temperature greater than about 10° C. to give an organometallic complex-containing mixture. When combined with exceptionally low levels of an activator (e.g., methyl alumoxane), the mixture actively polymerizes olefins to give polymers with a favorable balance of physical properties, including low density and narrow molecular weight distribution.

摘要： A catalyst system useful for polymerizing olefins is disclosed. It comprises an activator and an organometallic complex. The complex includes a Group 3-10 transition or lanthanide metal and a 1,3-bis(arylimino)isoindoline or 1,3-bis(heteroarylimino)isoindoline ligand. Activities of the Group 8-10 catalyst systems rival or exceed those of late transition metal bis(imines). The resulting polyolefins typically have high molecular weights, broad molecular weight distributions, and a high degree of crystallinity, which makes them valuable for film applications.

The process is performed with a supported quinolinoxy-containing single-site catalyst in the presence of a non-alumoxane activator, but in the absence of an &agr;-olefin, an aromatic solvent, and hydrogen. The process significantly increases the catalyst activity and the UHMWPE produced has improved tensile and impact properties.

摘要： A process for polymerizing unsaturated monomers is disclosed. The process comprises polymerizing, in the presence of a late transition metal catalyst (LTMC), a variety of unsaturated monomers which are traditionally, some of which are exclusively, made by free radical polymerizations. The LTMC polymerization provides the polymer with improved properties such as no free radical residue and narrow molecular weight distribution.

摘要： A method for making supported single-site catalysts useful for olefin polymerization is disclosed. An organometallic complex that contains a nitrogen-functional heterocyclic ligand is first prepared and reacted with an alumoxane. This product is then combined, preferably with high-intensity mixing, with a slurry of inorganic support, followed by solvent removal to give a supported catalyst. By introducing the alumoxane at the right time during preparation, and by judicious selection and chemical treatment of the inorganic support, one can make catalysts with high activity and good aging properties. The supported catalysts give olefin polymers with a favorable balance of physical properties, including low density, narrow molecular weight distribution, good melt-flow properties, and high bulk density.

摘要： Methods for making Group VIII metal bis(imine) complexes are disclosed. Each method uses a single reactor that is equipped with an internal filter to facilitate preparation and purification of the complex under an inert atmosphere. The complexes, which are useful in catalyst systems for olefin polymerization, are prepared in either one or two reaction steps. Surprisingly, the single-reactor approach to preparation and purification enables the efficient preparation of exceptionally high (>90%) yields of desirable Group VIII metal bis(imine) complexes.
