Abstract: A process for the preparation of a synthetic predominantly single carbon number hydrocarbon fluid comprises the steps of: contacting an alpha olefin having a carbon number of 4 to 30 with a single site catalyst under conditions effective to produce reactive hydrocarbon oligomers that contain reactive double bonds and comprising predominantly dimers, trimers, and tetramers wherein at least 10 weight percent of such reactive hydrocarbon oligomers at least one of trimers and tetramers; separating at least one of said trimers and tetramers in said reactive hydrocarbon oligomers; dimerizing said separated one of said trimers tetramers by contacting said separated one of said trimers or tetramers with a dimerization catalyst thereby producing an unsaturated synthetic hydrocarbon fluid; and contacting said unsaturated synthetic hydrocarbon fluid with hydrogen in the presence of a hydrogenation catalyst thereby producing a synthetic hydrocarbon fluid having predominantly single carbon number.

Abstract: Polymer suspensions prepared with non-aqueous, oil-free carrier fluids, for use in oil or gas well servicing. The polymer suspensions typically comprise a hydrophilic polymer, an organic clay, a stabilizer, and a carrier fluid selected from propylene glycol and butylene glycol. The addition of isopropyl alcohol, a polar activator, lowers the viscosity of the suspension. The further addition of neopentyl glycol further lowers viscosity and improves cross-linking of the polymer. The composition is both stable and environmentally acceptable.

Abstract: One or more oligomers of an olefin are prepared in the presence of a single-site catalyst. Preferably, the olefin is an ?-olefin, and the oligomers are a poly-alpha-olefin (PAO). The PAO so prepared is completely or substantially free of tertiary hydrogen resulting from isomerization. Consequently, the PAO possesses improved biodegradability, improved oxidation resistance, and/or a relatively higher viscosity index. The PAO has many useful applications, such as a component of a lubricant.

Abstract: A novel series of copolymers and terpolymers, useful as base oils for synthetic lubricants, are produced by polymerization of ethylene, an alpha-olefin, and optionally a third monomer comprising an alpha-olefin of 3 to 20 carbon atoms, in the presence of a combination catalyst comprising a compound of a transition metal of Group IVb of the Periodic Table and an aluminoxane. The copolymer or terpolymer may be further processed by thermal cracking to yield novel cracked polymers, and the cracked polymers may be hydrogenated. The copolymers or terpolymers may also be hydroisomerized. All the polymers are useful as base oils for lubricating oils and consumer products.

Abstract: Various vinylidene-containing polymers are obtained in the presence of a single-site catalyst. For example, the polymers include ethylene/isobutene copolymer, ethylene/propylene/isobutene terpolymer, ethylene/styrene/isobutene terpolymer, ethylene/&agr;-methyl-styrene/isobutene terpolymer, propylene/isobutene copolymer, styrene/isobutene copolymer, and &agr;-methyl-styrene/isobutene copolymer. These polymers may be used to formulate lubricant oils.
