Crosslinkable polymeric compositions comprising an ethylene-based polymer, an organic peroxide, and an amine-functionalized interpolymer. Such crosslinkable polymeric compositions and their crosslinked forms can be employed as polymeric layers in wire and cable applications, such as insulation in power cables.

A polyolefin composition is foamed by a process in which a nucleator is used, and the nucleator comprises 80% or more of unagglomerated fluororesin particles and/or agglomerates of fluororesin particles in which both the unagglomerated particles and the agglomerates are less than 1 μm in size.

Moisture-crosslinkable compositions having an alkoxysilane functionalized ethylenic polymer, a polymeric brominated flame retardant, antimony trioxide, and a silanol condensation catalyst. The polymeric brominated flame retardant and the antimony trioxide are present in quantities sufficient to provide a molar ratio of antimony to bromine (Sb/Br) in the range of from 0.79 to 1.70. Additionally, the polymeric brominated flame retardant and the antimony trioxide are present in the composition in a combined amount of greater than 35 wt %. Such moisture-crosslinkable compositions are suitable for use in preparing crosslinked articles of manufacture, such as for wire-and-cable applications.
