Abstract: A method of making a homogeneous mixture of polyolefin solids and an organic peroxide without melting the polyolefin solids during the making. The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the organic peroxide for a period of time sufficient to substantially intermix the polyolefin solids and the organic peroxide together while maintaining temperature of the heterogeneous mixture below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.

Abstract: Crosslinkable polymeric compositions for use in, for instance, cable insulation layers, 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-piperidinyloxyl ("TEMPO"), 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.
