Abstract: Free radically crosslinked, electrically conductive compositions exhibiting a highly stable volume resistivity comprise an olefin multiblock copolymer (OBC) having a high, e.g., greater than 20 mole percent comonomer content, e.g., butylene or octene, and carbon black. These compositions exhibit a highly stable volume resistivity relative to a composition similar in essentially all aspects save that the high comonomer OBC is replaced with a low comonomer OBC of similar density and melt index.

Abstract: Polymeric compositions having a slip agent comprising a silicone and a fatty acid amide. Such polymeric compositions can exhibit lower coefficients of friction when compared to polymeric compositions containing either silicone or fatty acid amide alone. Such polymeric compositions are suitable for use in various articles of manufacture, including, for example, wire and cable jackets.

Abstract: Liquid cooling mediums employed to immersion-cool electronic hardware devices. Such liquid cooling mediums have a flash point of at least 190 °C, as determined according to ASTM D92, and a viscosity of 27 centistokes ("cSt") or less at 40 °C, as determined according to ASTM D445. Such liquid cooling mediums can be employed to immersion-cool such devices as computer servers, server motherboards, and microprocessors.
