Abstract:
Provided is a block copolymer having an "A" block of a functionalized hydrocarbon moiety including one or more functional end groups selected from the group consisting of: epoxides, amines, acids, acid chlorides, acid anhydrides, halogens, vinyl or vinylidene double bond, aromatic rings and thiols, and a "B" block of a functionalized polyether moiety including one or more functional end groups selected from the group consisting: epoxides, amines, acids, acid chlorides, acid anhydrides, halogens, vinyl or vinylidene double bond, aromatic rings and thiols. The end group of the polyether moiety is different than the end group of the hydrocarbon moiety, and the hydrocarbon moiety and the polyether moiety are copolymerizable therewith. Preferably, the hydrocarbon moiety is a poly-α-olefm and the polyether moiety is a polyalkylene glycol.
Abstract:
This invention relates to processes to produce liquid poly-alpha-olefins (PAOs) having a kinematic viscosity at 100 0 C of more than 20 cSt in the presence of a metallocene catalyst with a non-coordinating anion activator and hydrogen.
Abstract:
The invention is directed to a process for producing polyolefins by one or more homogeneous or colloidal polymerization catalyst wherein residual catalyst is removed by using a solid sorbent.
Abstract:
This invention relates to a hydroxyaromatic functionalized polyalpha-olefin comprising the product of the combination of: a) a polyalpha-olefin comprising one or more C3 to C20 linear alpha-olefins and having at least 10 % vinylidene unsaturation, a viscosity index of 80 to 400, an Mn of 300 to about 20,000, and a pour point of 0 °C or less; and b) a hydroxyaromatic moiety; wherein the aniline point of the functionalized polyalpha-olefin is at least 10°C lower than the aniline point of the polyalpha-olefin.
Abstract:
Liquid poly-alpha-olefins are obtained by a) contacting in a reaction zone, alpha- olefin monomers with a non-coordinating anion activator, a single bridged meso-metallocene transition metal compound, and a co-activator, and ethylene is not present at more than 30 volume % of the monomers entering the reaction zone, and the alpha-olefm monomers in the feed components are present in at least 20 wt % or more based upon the weight of the meso- metallocene, non-coordinating anion activator, co-activator, monomers, and solvent or diluent, and where no more than 5% monomer is converted from olefin to alkane. The liquid polyalphaolefin product has a pour point of less than 25°C, a KV1oo of 2 to 6000 cSt, 20 weight percent dimer or less and a viscosity index of 60 or more.

Abstract:
The present invention is directed to a method for improving the performance of lubricating oils of high viscosity comprising GTL base stock(s) and/or base oil(s) and lubricating oil comprising such base stock(s) and/or base oil(s) in combination with an effective amount of a polyolefln fluid having a kinematic viscosity at 10O0C in the range between about 10 to about 200 mm 2 /s.
Abstract:
Polyolefins made in accordance with the present invention are produced by polymerizing an unsaturated olefin or combination of unsaturated olefins to produce an unsaturated polyolefin, isomerizing the unsaturated polyolefin in the presence of an acid catalyst under conditions to produce a substantially unsaturated-isomerized polyolefin, and hydrogenating the unsaturated-isomerized polyolefin to produce a saturated isomerized polyolefin. A lube oil comprising the inventive saturated isomerized polyolefin is also disclosed.
Abstract:
A lubricant formulation and method of blending a lubricant formulation is disclosed. The lubricant formulation comprises at least two base stocks. The first base stock comprises a viscosity greater than 135 cSt, Kv100°C and a tight molecular weight distribution as a function of viscosity. The second base stock comprises a viscosity less than 60 cSt, Kv100°C. The formulation also comprises a polyol ester. The lubricant formulation provides favorable properties.
