CA 2566855

The present invention relates to a continuous gas phase process comprising polymerizing one or more hydrocarbon monomer(s) in a fluidized bed reactor in the presence of catalyst system or polymerization catalyst and a condensable fluid for a period of at least 12 hours where the bed temperature is less than the Critical Temperature and the dew point temperature of the gas composition in the reactor is within 25 ~C of the bed temperature.

L'invention concerne un procédé en phase gazeuse continu consistant à polymériser au moins un monomère hydrocarboné dans un réacteur à lit fluidisé, en présence d'un système catalyseur ou d'un catalyseur de polymérisation et d'un fluide condensable, pendant au moins 12 heures, la température du lit étant inférieure à la température critique, la température du point de rosée de la composition gazeuse dans le réacteur se situant sur une plage de 25 °C de la température du lit.
