  • Process for the continuous gas-phase (co-) polymerisation of olefins in a fluidized bed reactor
    Patent number: 6646074
    Abstract: A process for the continuous gas-phase (co-)polymerisation of olefins in a fluidised bed reactor using a Ziegler-Nata type catalyst wherein the polymerisation is performed in the presence of a process aid additive selected from at least one of (1) a polysulphone copolymer; (2) a polymeric polyamine or (3) an oil-soluble sulphonic acid.

  • Gas phase polymerization process
    Patent number: 6359084
    Abstract: A process for the gas phase polymerization of one or more alpha-olefins conducted in the presence of a catalyst in a reactor having a fluidized bed, in which process, one or more zones having a temperature greater than the average bed temperature are formed at or in close proximity to the reactor wall, comprising the step of deactivating said zones by the introduction into the reactor of an effective quantity of carbon monoxide.
