Abstract: Cross-linkable polymeric compositions having an ethylene-based polymer, an organic peroxide, and a polyallyl cross-linking coagent, where the polyallyl cross-linking coagent and the organic peroxide are present in amounts sufficient to provide an allyl-to-active oxygen molar ratio of at least 1.6, based on the allyl content of the polyallyl cross-linking coagent and the active oxygen content of the organic peroxide. Such cross-linkable polymeric compositions can be employed in forming coated conductors.

Abstract: An ethylene-based polymer composition includes units derived from ethylene, units derived from a comonomer, and an optionally units derived from a termonomer. The comonomer is a monocyclic organosiloxane (MOCOS) of formula (I) [R1, R2SiO2/2]n wherein n is an integer greater than or equal to 3, each R1 is independently a (C2-C4) alkenyl or a H2C═C(R1a)—C(═O)—O—(CH2)m— wherein R1a is H or methyl, m is an integer from 1 to 4, and each R2 is independently H, (C1-C4) alkyl, phenyl, or R1.
