Abstract
Abstract A composition comprising an ethylene containing polymer, a crosslinking agent and a treated filler material. The treated filler material comprises a treating agent which is a polymer comprising acrylonitrile and at least one other monomer. A preferred treated filler material is a treated carbon black and a preferred ethylene containing polymer is an ethylene vinyl acetate (EVA) polymer. A semiconductive composition of the present invention may be advantageously utilized in electrical wire and cable application.
