Abstract

Il est décrit un procédé de polymérisation en solution amélioré dans lequel le poids moléculaire dun produit dinterpolymère déthylène peut être augmenté par rapport à un procédé comparatif; ou à un poids moléculaire dinterpolymère déthylène constant, le procédé amélioré peut être mis en uvre à une température de polymérisation plus élevée par rapport au procédé comparatif. Il est aussi décrit un procédé de polymérisation en solution amélioré dans lequel un produit interpolymère déthylène à une densité cible peut être produit à un rapport pondéral [a-oléfine/éthylène] inférieur dans le réacteur, par rapport à un procédé comparatif. Le solvant de procédé, léthylène, les comonomères facultatifs, lhydrogène facultatif et une formulation de catalyseur métallocène ponté sont injectés dans un ou plusieurs réacteurs pour former le produit interpolymère déthylène. Le catalyseur est ensuite désactivé, la solution est éventuellement passivée et après un procédé de séparation de phases, le produit interpolymère déthylène est récupéré.
