Abstract
Process for the extrusion of cross-linked polyethylene, which is characterized by the fact of forming a mixture with polyethylene, and 10 to 35% of the amount of a peroxide necessary to obtain an effective cross-linking, in which peroxide each of the peroxidic oxygens is bound directly with a tertiary carbon atom whose remaining valencies are attached to radicals selected from the group consisting of alkyl, cycloalkyl, alkyl-cycloalkyl, aryl and aralkyl, cure this mixture to form a gel structure, mix with it the remaining peroxide, extrude the resulting composition and put it in contact with steam at the curing temperature in order to obtain the hardening thereof.
