Abstract:
A process for preparing an electrical cable comprising at least one conductor and at least one layer of extruded insulating coating, comprising:a) coating, by extrusion, the conductor with a polymeric composition comprising a polyethylene, a radical initiator and at least one unsaturated carboxylic acid of general formula (I) in free form: â€ƒin which: R1 represents H or OH3; n represents 0 or 1; said unsaturated carboxylic acid being present in an amount of between 0.0006% and 0.25% by weight, said amount being expressed as the weight content of â€”COOH groups relative to the total weight of the polymetric composition; and b) heating the conductor thus coated so as to obtain cross-linking of said polymeric composition.
