Title of Invention	POLYMERISATION PROCESS
Abstract	The present invention relates to a polymerisation process and in particular to a process for the copolymerisation of ethylene and an α-olefin comonomer having 7 to 10 carbon atoms in a fluidised bed gas phase reactor in the presence of a multi-site Ziegler-Natta polymerisation catalyst characterised in that (i) said process is operated in condensed mode, (ii) the amount of said α-olefin is maintained below that at which substantial condensation in the reactor occurs and (iii) at least one of the following apply: a) the catalyst has an uptake rate of 1-octene of at least 700; b) the polymerisation is performed in the presence of an activity promoter.
