Abstract: Processes to prepare branched polyolefins for lubricant applications comprise combining at least one olefin and a coordination-insertion catalyst under conditions such that at least one oligomer product is formed. Low molecular weight by-products are fractionated out and the oligomer product is converted to a saturated hydrocarbon via hydrogenation.

Abstract: Disclosed is an effective thermal grease comprising a hyperbranched olefinic fluid and a thermally conductive filler. Property-modifying additives and fillers may also be included. The hyperbranched olefinic fluid is selected to have an average of at least 1.5 methine carbons per oligomer molecule and at least 40 methine carbons per one thousand total carbons. The thermal grease exhibits a flash point of 180° C. or higher, a pour point of 0° C. or lower, and a kinematic viscosity at 40° C. of no more than 200 cSt (0.0002 m 2/s). The composition may offer improved thermal conductivity, reduced tendency to migrate, and lower cost when compared with many other thermal greases, including silicone-based thermal greases.

Abstract: A process to prepare a relatively inexpensive utility fluid comprises contacting together ethylene and a coordination-insertion catalyst and, optionally, an alpha-olefin, in a continuously-fed backmixed reactor zone under conditions such that a mixture of a hyperbranched oligomer and a branched oligomer is formed. The hyperbranched oligomer has an average of at least 1.5 methine carbons per oligomer molecule, and at least 40 methine carbons per one-thousand total carbons, and at least 40 percent of the methine carbons is derived from the ethylene, and the average number of carbons per molecule is from 25 to 100, and at least 25 percent of the hyperbranched oligomer molecules has a vinyl group and can be separated from the branched oligomer, which has an average number of carbons per molecule of up to 20. The coordination-insertion catalyst is characterized as having an ethylene/octene reactivity ratio up to 20 and a kinetic chain length up to 20 monomer units.

Abstract: Catalyst systems for olefin polymerization include a metal-ligand complex of a general formula (I). The metal-ligand complex of formula (I) is a transition metal complex of titanium, zirconium, or hafnium, in which the transition metal is coordinated with a biaryl phenoxy ligand structure. Olefin polymerization processes include contacting ethylene and optionally one or more (C3-C12) alpha-olefins in the presence of the catalyst system to produce an ethylene-based polymer or copolymer.
