Title (EN) PROCESS FOR PRODUCING POLYETHYLENE COMPOSITION
(FR) PROCÉDÉ DE FABRICATION D'UNE COMPOSITION DE POLYÉTHYLÈNE
Abstract:
(EN) The present invention is directed to a process for producing by extrusion a polymer composition and to a use of a polyethylene (PE) having SHI (2.7/210) of at least 10 (when measured as described above under Determination methods) for reducing the gel content of a polyethylene polymer produced in the presence of a coordination catalyst.
(FR) La présente invention concerne un procédé pour produire par extrusion une composition polymère ainsi qu'une utilisation d'un polyéthylène (PE) ayant un indice SHI (2,7/210) d'au moins 10 (mesuré comme décrit ci-dessus en cours selon des procédés de détermination) permettant de réduire la teneur en gel d'un polymère de polyéthylène produit en présence d'un catalyseur de coordination.
