Title (EN) METHOD FOR PRODUCING VERY-HIGH OR ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE
(FR) PROCÉDÉ DE PRODUCTION DE POLYÉTHYLÈNE DE MASSE MOLÉCULAIRE TRÈS ÉLEVÉE OU ULTRA-ÉLEVÉE
Abstract:
(EN) The field of the invention relates generally to a method for preparing very-high or ultra-high molecular weight polyethylene. More particularly, the present invention related to a method of preparing very-high or ultra-high molecular weight polyethylene using a supported catalyst comprising a support, an activator and a metal-ligand complex, as well as the catalyst itself. The present invention additionally relates to a method of using a supported catalyst comprising a support, an activator and co-supported metal-ligand complexes to obtain a bi-modal molecular weight distribution of polyethylene.
(FR) L'invention concerne d'une manière générale un procédé de préparation d'un polyéthylène de masse moléculaire très élevée ou ultra-élevée. Plus particulièrement, la présente invention porte sur un procédé de préparation d'un polyéthylène de masse moléculaire très élevée ou ultra-élevée à l'aide d'un catalyseur supporté comprenant un support, un activateur et un complexe métal-ligand, ainsi que sur le catalyseur lui-même. La présente invention porte de plus sur un procédé d'utilisation d'un catalyseur supporté comprenant un support, un activateur et des complexes métal-ligand co-supportés pour obtenir une distribution bimodale de masses moléculaires de polyéthylène.
