Title: CROSSLINKABLE POLYMERIC COMPOSITIONS WITH METHYL-RADICAL SCAVENGERS AND ARTICLES MADE THEREFROM
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.
