<p>A process for the gas phase polymerisation of one or more alpha-olefins in the presence of a polymerisation catalyst system under reactive conditions in a fluidised bed reactor which process comprises introducing into the reactor a deactivating agent characterised in that the deactivating agent is introduced close to the reactor wall and that said introduction does not terminate the polymerisation reaction. <IMAGE> <IMAGE></p> |
