  • Method of producing an electrically semi-conducting, strippable plastics mixture
    Patent number: 4915889
    Abstract: An electrically semi-conducting, strippable coating material for electric wires and cables is produced by intimately mixing a premix of a polyolefin with an unsaturated organic silane, a free-radical-forming organic compound and optionally plastics additives in a hot state, until the unsaturated organic silane has reacted significantly with the polyolefin and/or the copolymerizate of olefins, preferably for 1/2-30 min. at 180.degree.-230.degree. C., and subsequently admixing comminuted carbon while the mixture is still hot.
