Abstract: Cross-linkable polymeric compositions comprising 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: 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.

Abstract: A die assembly (5) including: (i) a die plate (10) having an inlet surface (15) and an opposing discharge surface(35); (ii) an inlet (30) on the inlet surface (15) and a first axis of symmetry(A) extending through the inlet (30) and perpendicular to the inlet surface (15); (iii) a discharge port (45) on the discharge surface (35) and a second axis of symmetry (B) extending through the discharge port (45) and perpendicular to the discharge surface (35). The first and second axes are apart from, and parallel to, one another. The die assembly (5) includes (iv) an extrudate passage (42) fluidly connecting the inlet (30) and the discharge port (45). A third axis of symmetry (C) extends through the extrudate passage (42). The die assembly (5) includes (v) a nozzle (100) mounted in the die plate (10), the nozzle (100) having an injection tip (110) in the extrudate passage (42) at the discharge port (45); and (vi) the third axis of symmetry (C) intersects the first axis of symmetry (A) to form an acute angle.
