Abstract: A macromonomer precursor is provided that includes a polymeric chain derived from farnesene and a single functional terminal end. The functional terminal end may include a hydroxyl group, an amino group, an epoxy group, an isocyanato group, or a carboxylic acid group. The terminal end of the macromonomer precursor may then be reacted with a (meth)acrylate to form a macromonomer having a (meth)acrylate functionalized terminal end that may be (co)polymerized with radically polymerizable monomers, such as alkyl(meth)acrylate monomers. Alternatively, a copolymer may be obtained by first deriving a poly(meth)acrylate from (meth)acrylate monomers having reactive groups that would allow the macromonomer precursors to be grafted onto the poly(meth)acrylate in a second step. The resulting copolymer may be incorporated as an additive in various formulations, such as a lubricant, a hydraulic fluid, a cosmetic composition, and an adhesive composition.

Abstract: A non-water-based tire lubricant includes a thickening agent and a thinning agent. The thickening agent may be a silicone grease, hydrotreated light petroleum distillates, or hydrogenated liquid rosin ester, and the thinning agent may be a blend of petroleum distillates and additives or a silicone liquid. The tire lubricant has a pliable consistency, is easier to apply and use than standard tire lubricants, allows the tire to seal at much lower pressures, and is not water-based so that nitrogen concentrations inside the tire are maintained at 100 percent.
Abstract: A method for preventing or reducing low speed pre-ignition in an engine lubricated with a lubricating oil while maintaining or improving cleanliness by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and at least one boron-containing compound and at least one overbased calcium detergent as minor components. The at least one boron-containing compound includes at least one borated dispersant, or a mixture of a boron-containing compound and a non-borated dispersant. The boron to nitrogen ratio for the at least one boron-containing compound is less than or equal to about 0.3 and the lubricating oil is essentially free of elemental magnesium. The lubricating oils of this disclosure are particularly advantageous as passenger vehicle engine oil (PVEO) products.
