Abstract: Olefin polymerization in the presence of heterogeneous supported catalysts is improved by incorporating into the supported catalyst a unifunctional hydrophobic tether comprising a hydrophobic portion containing no basic nitrogen and a univalent reactive group. The unifunctional hydrophobic tether reduces fouling and sheeting in gas phase polymerization processes and improves polymer morphology and bulk density in slurry polymerization processes, while substantially maintaining or enhancing catalyst polymerization activity.

Abstract: A method for making a chiral transition metal-ligand catalyst complex that is active in catalyzing stereoselective ring opening reactions includes contacting an asymmetric tetradentate ligand, in an excess of a Brnullnsted acid, with a salt of a first row transition metal, wherein the acidity of the conjugate acid of the salt is the same as or less than the acidity of the Brnullnsted acid, under conditions effective to allow formation of the active chiral transition metal-ligand catalyst complex, and forming a solution of the complex in a water-miscible, protic solvent from which the active complex can be precipitated by the addition of water and adding water to the solution to precipitate at least a portion of the complex.
