Abstract: Silane-crosslinkable polymeric compositions comprising a polyolefin having hydrolyzable silane groups, an acidic silanol condensation catalyst, and a phenolic antioxidant. The phenolic antioxidant has a phenol-based moiety fused with a cyclic ether where the oxygen atom of the cyclic ether is located in the para position relative to the hydroxyl group of the phenol-based moiety. Such crosslinkable polymeric compositions can be employed in various articles of manufacture, such as in the wire and cable industry.

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.
