Title
(EN) GAS PHASE PRODUCTION OF POLYDIENES
(FR) PRODUCTION EN PHASE GAZEUSE DE POLYDIENES
Abstract
(EN)
A process for producing polybutadiene or polyisoprene in a gas phase reactor by continuously introducing a stream of butadiene or isoprene monomer and optionally an inert gas into a polymerization zone while maintaining the temperature within the polymerization zone below the dew point temperature of the monomer present in said polymerization zone in the presence of a rare earth catalyst and in the presence of inert particulate material.
(FR)
Procédé de production de polybutadiène ou de polyisoprène dans un réacteur à phase gazeuse par introduction continue d'un courant de monomère de butadiène ou d'isoprène et, éventuellement, d'un gaz inerte dans une zone de polymérisation, tandis que la température à l'intérieur de ladite zone et maintenue au-dessous de la température au point de rosée du monomère présent dans ladite zone, en présence d'un catalyseur des terres rares et en présence d'un matériau inerte particulaire.
