| description | The present invention provides a method for tailoring the molecular weight distribution of a multimodal (e.g. bimodal) ethylene polymer having a lower molecular weight component and a higher molecular weight component comprising polymerising ethylene and optionally at least one further alpha olefin in at least two stages, wherein at least one stage is carried out in a slurry phase in the presence of a Ziegler Natta catalyst comprising an electron donor which is an ether.
L'invention concerne un procédé permettant d'adapter la distribution du poids moléculaire d'un polymère d'éthylène multimodal (par exemple, bimodal) comprenant un composant de poids moléculaire inférieur et un composant de poids moléculaire supérieur et consistant à polymériser l'éthylène et éventuellement au moins une autre alpha oléfine en au moins deux étapes, au moins une étape étant effectuée dans une phase de boue en présence d'un catalyseur de Ziegler Natta comprenant un donneur d'électron: un éther. |
