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: 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: 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.
