The present disclosure provides base stocks and or diesel fuel, and processes for producing such base stocks and or diesel fuel by polymerizing alpha-olefins and internal olefins. The present disclosure further provides polyolefin products useful as base stocks and or diesel fuel. In at least one embodiment, a process includes: i) introducing, neat or in the presence of a solvent, a feed comprising a branched C-Cinternal olefin, with a catalyst compound comprising a group 8, 9, 10, or 11 transition metal and at least one heteroatom and ii) obtaining a C-Cpolyolefin product having one olefin, a methylene content of from about 1 wt % to about 98 wt %, and or a methyl content of from about 1 wt % to about 75 wt %. The feed may further include a linear C-Cinternal olefin, a C-Calpha-olefin, or a mixture thereof.

Processes for polymerizing alpha-olefins, internal olefins and compositions thereof

The present disclosure provides base stocks and processes for producing such basestocks by polymerizing internal olefins. The present disclosure further provides base stocks, comprising low molecular weight polyolefin products, having one or more of improved flow, low temperature properties, and thickening efficiency. The present disclosure further provides polyolefin products useful as base stocks and or diesel fuel. In at least one embodiment, a process includes introducing a feedstream comprising C-Cinternal-olefins with a catalyst system comprising a nickel diimine catalyst optionally in the presence of a solvent. The method includes obtaining a C-Cpolyolefin product having one or more of a carbon fraction of epsilon-carbons of from about 0.08 to about 0.3, as determined byC NMR spectroscopy, based on the total carbon content of the polyolefin product.

Methods are provided for producing Group III base stocks having high viscosity and also having one or more properties indicative of a high quality base stock. The resulting Group III base stocks can have a viscosity at 100&#xb0; C. and/or a viscosity at 40&#xb0; C. that is greater than the corresponding viscosity for a conventional Group III base stock. Additionally, the resulting Group III base stocks can have one or more properties that are indicative of a high quality base stock.

High viscosity base stock compositions

Methods are provided for producing Group II base stocks having high viscosity and also having one or more properties indicative of a high quality base stock. The resulting Group II base stocks can have a viscosity at 100&#xb0; C. and/or a viscosity at 40&#xb0; C. that is greater than the corresponding viscosity for a conventional Group II base stock. Additionally, the resulting Group II base stocks can have one or more properties that are indicative of a high quality base stock.

This invention relates in certain aspects to a process for removing oxygenates from a stream, preferably a hydrocarbon stream comprising contacting an organosilica material with the hydrocarbon steam, where the organosilica material is a polymer of at least one monomer of Formula [ZOZSiCH], wherein Zrepresents a hydrogen atom, a C-Calkyl group, or a bond to a silicon atom of another monomer and Zrepresents a hydroxyl group, a C-Calkoxy group, a C-Calkyl group or an oxygen atom bonded to a silicon atom of another monomer.

Methods are provided for producing Group I base stocks having high viscosity and also having one or more properties indicative of a high quality base stock. The resulting Group I base stocks can have a viscosity at 100&#xb0; C. and/or a viscosity at 40&#xb0; C. that is greater than the corresponding viscosity for a conventional Group I bright stock formed by solvent processing. Additionally, the resulting Group I base stocks can have one or more properties that are indicative of a high quality base stock.

This invention relates to a polyolefin comprising one or more aromatic moieties according to the following formulae: wherein the PO is the residual portion of a vinyl terminated macromonomer (VTM) having had a terminal unsaturated carbon of an allylic chain and a vinyl carbon adjacent to the terminal unsaturated carbon;

A process for making a substantially saturated dendritic hydrocarbon polymer. The process has the following steps: (a) polymerizing an amount of one or more alkadiene monomers and/or one or more alkenylaromatic polymers under anionic conditions in the presence of a di- or tri-functional organic lithium initiator to produce a polyalkadiene defining a multiplicity of lithiated chain ends; (b) reacting the polyalkadiene with an amount of a tri- or di-functional silane coupling agent to form a dendritic polyalkadiene; and (c) hydrogenating the dendritic polyalkadiene to form a substantially saturated dendritic hydrocarbon polymer. Also a process for process for making a dendritic hydrocarbon polymer, comprising: (a) polymerizing an amount of one or more alkadiene monomers and/or one or more alkenylaromatic polymers under anionic conditions in the presence of a di- or tri-functional organic lithium initiator to produce a hydrocarbon polymer defining a multiplicity of lithiated chain ends; and (b) reacting the hydrocarbon polymer with an amount of a tri- or di-functional silane coupling agent to form a dendritic hydrocarbon polymer.
