Patent

CA 2198144

The invention is directed toward polymerizing or copolymerizing alpha-olefins either alone or in combination with one or more other alpha-olefins in the presence of a metallocene catalyst in a gas phase reactor having a fluidized bed and a fluidizing medium such that the fluidizing medium entering the reactor comprises a gas and a liquid phase.

La présente invention concerne un procédé de polymérisation ou de copolymérisation d'.alpha.-oléfines soit seules, soit combinées avec une ou plusieurs autres .alpha.-oléfines en présence d'un catalyseur métallocène dans un réacteur à phase gazeuse comportant un lit fluidisé et un milieu de fluidisation tels que le milieu de fluidisation entrant dans le réacteur est constitué d'une phase gazeuse et d'une phase liquide.
