    Abstract: The invention relates to a method of making a crosslinkable ethylene polymer sheet by taking a film of carboxyl-containing ethylene polymer, which is preferably an ethylene-acrylic acid-alkyl acrylate terpolymer or a graft copolymer of ethylene polymer and carboxyl-containing monomer, and applying to it at from room temperature to +45 DEG C, preferably with the aid of pressure systems, a liquid organic peroxide in a uniform manner in amounts of from 0.3 to 3.0 % by weight and allowing the peroxide to diffuse into the film, and to the use of the crosslinkable ethylene copolymer sheet for making a layered material by placing the adhesive sheet between two cover sheets and heating while employing a small amount of pressure.

    Abstract: The invention relates to an electrical high-voltage cable of 1 to 500 kV, the cable insulation being resistant towards the formation or growth of water trees and consists of 70 to 99 parts by weight of an ethylenepolymer (I) and 1 to 30 parts by weight of an ethylenecopolymer (II) which consists of 80 to 92 parts by weight of ethylene and 8 to 20 parts by weight of C4-C10- alpha -olefins with a density of 0.890 to 0.915 g/cm and a crystalline melting point of 90 to 125 DEG C.
