Abstract: Cross-linkable polymeric compositions comprising an ethylene-based polymer, an organic peroxide, an optional cross-linking coagent, and an antioxidant. Such cross-linkable polymeric compositions are prepared by imbibing at least a portion of the organic peroxide, the optional cross-linking coagent, and the antioxidant into the ethylene-based polymer. Such cross-linkable polymeric compositions can be employed in forming coated conductors.

Abstract: Crosslinkable polymeric compositions for use in, for instance, cable insulation layers, are disclosed. The crosslinkable polymeric compositions 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-piperidinyloxy (“TEMPO”), such as 4-acryloxy-2, 2, 6, 6-tetramethylpiperidine-N-oxyl, 4-allyloxy-2, 2, 6, 6-tetramethylpiperidine-N-oxyl, and bis (2, 2, 6, 6-tetramethyl-1-piperidinyloxy-4-yl) sebacate, and combinations of two or more thereof, 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 conductor 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.

Abstract: Processes for making cables and cable cores having a crosslinked insulation layer. The processes comprise (a) providing an initial cable core having a conductor, a first semiconductive layer, an initial insulation layer comprising a crosslinkable polymeric composition, and a second semiconductive layer, and (b) subjecting the initial cable core to a crosslinking process. The crosslinkable polymeric composition comprises an ethylene-based polymer, an organic peroxide, and a polyallyl crosslinking coagent. The polyallyl crosslinking coagent and the organic peroxide are present in amounts sufficient to provide an allyl-to-active oxygen molar ratio of less than 1.2.
