GAS PHASE POLYMERIZATION METHOD

摘要

The invention relates to a method and device for polymerizing gaseous olefins, especially ethylene and at least one alpha -olefin, in the gas phase in an agitated or spun polymerization zone (2) that contains catalysts and in at least one relief zone (6, 10) connected to said polymerization zone (2). The mixture which exits the polymerization zone (2), and which consists of a solid (co)polymer and non-reacted monomers passes through, before the relief zone, a settling area that is configured, in particular, as a settling leg (14).
