    Abstract: A moisture-curable polyolefin formulation comprising a (hydrolyzable silyl group) -functional polyolefin prepolymer and a condensation-cure catalyst system comprising and/or made from mixture of a compound that is a carboxamidine or a guanidine and a compound that is a cobalt acetylacetonate or a zinc acetylacetonate, wherein each compound independently is unsubstituted or substituted. Also, methods of making and using same, a cured polyolefin made therefrom, and articles containing or made from same. Also, condensation-cure catalyst systems useful therein.

    Abstract: A composition comprises a) an ethylene-based copolymer comprising units derived from ethylene and units derived from at least one comonomer of Structure I, wherein R is a C1-C2 hydrocarbyl group and R' is a C1-C4 hydrocarbyl group; b) at least one antioxidant; c) from greater than 0 wt%to less than 3 wt%of an organic peroxide, based on the total weight of the composition; d) optionally, at least one co-agent; and e) optionally, at least one tree retardant, wherein the ethylene-based copolymer has a melt temperature (Tm) (?) and a comonomer content in moles per 100 grams ethylene-based copolymer (mol/100 g) (comonomer) that satisfies the relationship Tm

    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.
