    Abstract: A moulding material comprises a thermoplastic polymer of ethylenically unsaturated compounds and a compound of formula R-NH-COOR1 where R and R1 are C1- 20 aliphatic or unsubstituted or substituted C6- 20 aromatic groups. The polymer may be a copolymer of ethylene and vinyl acetate, ethyl acrylate or acrylonitrile, or polyethylene. The compound may be hexamethylene - 1,6 - bis - (alkyl or cycloalkylurethane), phenyl - stearyl - urethane, toluene-2,4 - bis - (n - octylurethane) or triphenylmethane - 4,41,411 - trioctylurethane and may be present in an amount of 0.01-2%. The moulding material may be mixed on rollers, on a calender or in an extruder, and may be granulated and then processed into a sheet. The composition may contain methanol as a solvent for the urethane.

    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.
