Abstract: Hot melt adhesives may comprise linear alpha olefins (LAOs) or LAO-derived compounds as an at least partial replacement for paraffinic white oil diluents. Such adhesive compositions may comprise an ethylenically unsaturated polymer or copolymer, a tackifier, and a diluent. The diluent may comprise at least one of: one or more C18+ linear alpha olefins (LAOs) having a kinematic viscosity of about 4 cSt or less at 135° C.; one or more LAO dimers formed from one or more C18+ LAOs, the one or more LAO dimers having an internal olefin and a kinematic viscosity of about 6 cSt or less at 135° C., or one or more paraffinic hydrocarbons having an even carbon number distribution and formed through dimerization of one or more C18+ LAOs and subsequent reduction. The one or more paraffinic hydrocarbons may have a kinematic viscosity (ASTM D-445) of about 4 cSt to about 8 cSt at 135° C.

Abstract: A method for controlling the growth of a hydraulic fracture using a stress shadow generated during a hydraulic fracturing operation includes selecting a stage pair including a first stage and a second stage for which hydraulic fractures are to be generated via a hydraulic fracturing operation. The method also includes hydraulic fracturing the first stage to generate a corresponding first hydraulic fracture and controlling a magnitude of a stress shadow originating from the first hydraulic fracture by varying at least one parameter of the hydraulic fracturing operation, where the stress shadow is controlled so as to provide a second hydraulic fracture of a target fracture shape for the second stage. The method further includes hydraulic fracturing the second stage to generate the second hydraulic fracture with the target fracture shape.

Abstract: A lubricant composition may be used as an engine oil. Such lubricant compositions may, for example, include: from about 25.0 mass % to about 99.8 mass % of an oil base stock, based on a total mass of the lubricant composition, the oil base stock including at least one bio-sourced basestock and at least one alkyl naphthalene; and wherein the lubricant composition includes about 0.05 mass % or less phosphorus, about 0.05 mass % or less sulfur, and about 0.5 mass % or less ash.

Abstract: The present disclosure relates to a method of forming a composition including forming a polymer melt in a melt feeder. The melt feeder is coupled with an extruder. The method includes introducing the polymer melt from the melt feeder to the extruder at a first location of the extruder. The method includes extruding the polymer melt through the extruder via a plurality of intermeshing screws disposed within the extruder. The method includes introducing a coupling agent to the extruder at a second location of the extruder.

PVC blending methods may comprise: combining PVC and a lubricant composition to form a mixture, and blending the mixture to form a lubricated PVC blend, in which the mixture contains an effective amount of the lubricant composition to provide a fusion temperature for the lubricated PVC blend of about 190° C. or below as determined by torque rheometry at 65 rpm. The lubricant composition may comprise one or more C18+ linear alpha olefins (LAOs) having a kinematic viscosity of about 4 cSt or less at 135° C., or one or more LAO dimers formed from the one or more C18+ LAOs, the one or more LAO dimers having an internal olefin and a kinematic viscosity of about 6 cSt or less at 135° C., or reduced LAO dimers.
