Abstract: A high molecular weight ethylene copolymer is prepared by high-pressure copolymerization of ethylene with an alpha , beta -ethylenically unsaturated carboxylic acid, carboxylic anhydride or a derivative thereof in the presence of a tertiary organic monoamine, preferably from 10 to 100 mol % thereof, based on the unsaturated carboxylic acid used, and can be used for preparing adhesion promoters and cable sheathing.

Abstract: Grafting of ethylenically unsatd. acids or anhydrides (or their derivs.) onto ethylene homo- or co-polymers of density 0.930 g/cc or higher is carried out in a conventional extruder or mixer at 1-500 bar in the absence of a catalyst which decomposes to give radicals. This is achieved by mixing 0.01-0.5 wt. pts. of the grafting monomer with 100 wt. pts. of molten ethylene polymer at 140 deg.C or above and then carrying out grafting at 210-300 deg.C..

Abstract: The copolymers comprise from 96 to 99.6 mol% of ethylene and from 0.4 to 4 mol% of a C3-C6-alkenecarboxylic acid or an ester of this acid having a total of up to 14 carbon atoms, or mixtures of these monomers, and are obtainable by polymerisation in a continuous tubular reactor at a pressure of from 500 to 5000 bar and at elevated temperature in the presence of initiators which decompose to form free radicals, by adding a mixture of said reaction components only at the inlet point of the tubular reactor, the temperature in a first reaction zone being limited to about 240 DEG C, further initiator being metered in at the beginning of a second reaction zone after the temperature has been reduced by from 5 to 20 DEG C, and the reaction being completed at temperatures of up to 300 DEG C.

Abstract: The invention relates to a process for the preparation of ionically crosslinked ethylene copolymers by mixing the carboxyl group-containing copolymers with an aqueous metal salt solution in the reaction zone of a twin-screw extruder and transferring the reaction mixture into a degassing zone, to an ionically crosslinked ethylene copolymer, and to its use as a coupling agent, injection-moulded article or coating film.
