Abstract

Linvention porte sur une cire de polyéthylène dune masse moléculaire moyenne en nombre de 1 000 à 10 000 et une répartition de la masse moléculaire de 2 à 4 qui peut être produite à laide dun catalyseur phosphinimine dans des conditions « forcées » de polymérisation en solution. Les conditions « forcées » comprennent des températures de polymérisation élevées, des efficacités de catalyseur comparativement faibles et des taux de conversion de léthylène très élevés. Ces conditions « forcées » peuvent être obtenues par le fonctionnement du réacteur à une température comprise entre 190 °C et 250 °C, à laide dune concentration élevée en catalyseur et dun taux de conversion de léthylène élevé. À laide de ces conditions, une cire de polyéthylène peut être produite en labsence dhydrogène.
