Abstract: A moisture-curable semiconductive formulation consisting essentially of a polyethylene-based polymer blend (uncured) and a conventional carbon black. The polyethylene-based polymer blend comprises a mixture of an ethylene/(alkenyl-functional hydrolyzable silane)/(optional olefinic hydrocarbon) copolymer and an ethylene/unsaturated carboxylic ester copolymer that is free of moisture curable groups. We also discovered methods of making and using same, a moisture-cured semiconductive product made therefrom, and articles containing or made from same.
