Title (EN) CONTINUOUS EXTRUDER PROCESS FOR MANUFACTURING RHEOLOGY-MODIFIED POLYOLEFIN FOR CABLE INSULATION LAYER, AND RELATED PRODUCTS
(FR) PROCÉDÉ CONTINU D'EXTRUSION POUR FABRIQUER UNE POLYOLÉFINE À RHÉOLOGIE MODIFIÉE POUR UNE COUCHE D'ISOLATION DE CÂBLE ET PRODUITS APPARENTÉS
Abstract:
(EN) Rheology-modified, additive-containing ethylenic polymer compositions are prepared in a continuously operated extruder comprising first, second and third zones by a process comprising the steps of: mixing in the second zone of the extruder an ethylenic polymer and a high-temperature decomposing peroxide at a temperature such that the half-life of the peroxide is equal to or greater than one minute and for a sufficient period of time to modify the rheology of the ethylenic polymer to produce a rheology-modified, melted ethylenic polymer for transfer to the third zone of the extruder; and adding to the third zone one or more additives to the rheology-modified, melted ethylenic polymer to produce the rheology-modified, additive-containing ethylenic polymer.
(FR) L'invention concerne des compositions de polymère éthylénique contenant un additif, à rhéologie modifiée, préparées dans une extrudeuse fonctionnant en continu comprenant une première, une deuxième et une troisième zone par un procédé comprenant les étapes consistant à : mélanger, dans la deuxième zone de l'extrudeuse, un polymère éthylénique et un peroxyde se décomposant à haute température, à une température telle que la demi-vie du peroxyde est égale ou supérieure à une minute, et pendant une durée suffisante pour modifier la rhéologie du polymère éthylénique en vue de produire un polymère éthylénique fondu, à rhéologie modifiée pour son transfert vers la troisième zone de l'extrudeuse ; et ajouter, dans la troisième zone, un ou plusieurs additifs au polymère éthylénique fondu à rhéologie modifiée pour produire le polymère éthylénique contenant un additif à rhéologie modifiée.
