摘要： Crosslinkable polymeric compositions for use in, for instance, cable insulation layers, comprise an ethylene-based polymer, an organic peroxide, a crosslinking coagent, and a methyl-radical scavenger comprising at least one derivative of 2, 2, 6, 6-tetramethyl-1-piperidinyloxyl (“TEMPO”), wherein ratio of crosslinking coagent to organic peroxide is less than 1.72:1 on a molar basis. A crosslinked article prepared from a crosslinkable polymeric composition is also disclosed, the crosslinkable polymeric composition comprising, inter alia, a methyl-radical scavenger comprising at least one TEMPO derivative. In addition, a coated conducttor comprising a conductive core and a polymeric layer at least partially surrounding the conductive core is disclosed, wherein at least a portion of the polymeric layer comprises the crosslinked article.

摘要： Thermally conductive materials comprising an olefin block composite and a thermally conductive filler, where the thermally conductive filler is present in an amount sufficient to increase the thermal conductivity of the olefin block composite relative to the olefin block composite in its neat state. Such thermally conductive materials can be used in various articles of manufacture, such as a thermal interface material or a molded heat dissipation component.

摘要： Optical cable components fabricated from an extrudable polymeric blend of crystalline polypropylene modified with one or more impact-modifying polymers. The impact-modifying polymers are crosslinked and can be selected from a polyolefin elastomer, an olefin multi-block interpolymer, an olefin block composite, and combinations thereof. Optionally, the polymeric blend can further comprise a compatibilizer. The polymeric blend may also contain one or more additives. The optical fiber cable components can be selected from buffer tubes, core tubes, and slotted core tubes.
