Abstract: A method of making a homogeneous mixture of polyolefin solids and liquid additive 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 liquid additive for a period of time sufficient to substantially intermix the polyolefin solids and the liquid additive together and while maintaining temperature of the heterogeneous mixture above the freezing point of the at least one liquid additive and below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.

Abstract: A method of making a homogeneous mixture of polyolefin solids and a particulate solid additive without melting the polyolefin solids or the particulate solid additive 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 particulate solid additive for a period of time sufficient to substantially intermix the polyolefin solids and the particulate solid additive together and while maintaining temperature of the heterogeneous mixture below the melting point of the at least one particulate solid additive and below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids or the at least one particulate solid additive.

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.
