| 摘要 |
<p>The present invention relates to a process for the gas phase polymerisation of one or more alpha-olefins conducted in the presence of a catalyst in a reactor having a fluidised 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, characterised in that said zones are deactivated by the introduction into the reactor of an effective quantity of a deactivating agent.</p> |
