  • Patent number: 9309337
    Abstract: Provided are blends of branched hydrocarbon comb polymers having tailored branching and molecular weight parameters, with substantially linear polymers. Such blends have been found to have improved extensional rheological properties, while maintaining nearly the viscosity of the substantially linear polymers. The blends of the hydrocarbon comb polymers with the substantially linear polymers thus maintain the extrusion processing characteristics of the linear polymer alone, but have improved extensional flow processability, with strain hardening ratios (SHR) greater than 1. The blends are effective in blown film processing. Also disclosed are related methods for improving extensional flow processability using the branched hydrocarbon comb polymers, as well as the branched hydrocarbon comb polymers themselves, including as a property enhancing additive for such substantially linear polymers.

  • Publication number: 20140038862
    Abstract: Provided are a lubricating engine oil and a method of improving wear protection in an engine lubricated with such lubricating oil. The method includes using as the lubricating oil a formulated oil comprising a lubricating oil base stock as a major component, an antiwear additive as a first minor component, and carbon nanoplatelets as a second minor component. The carbon nanoplatelets are dispersed in said lubricating oil base stock. Wear protection is improved as compared to wear protection achieved using a lubricating oil not containing carbon nanoplatelets as a second minor component. A synergy exists between carbon nanoplatelets and other major components of lubricants, especially with zinc dialkyldithiophosphate (ZDDP) or other phosphate antiwear additives, that helps to form a nano-composite wear resistant and low friction tribofilm both on ferrous and non-ferrous surfaces (e.g., carbon coatings, ceramic coatings, polymeric coatings, and the like) of engines/machines.
