The polymerisation of olefins in the gas phase carried out in the presence of a catalyst system comprising (a) a metallocene and (b) an activator is improved by the addition of a lower alkane to the reactor. The preferred alkane is pentane and is preferably added to the reactor as a liquid. The activity of the catalyst system may be improved by the addition of the alkane.
