Beschreibung
Zusammenfassung:	The present invention relates to a continuous gas phase process comprising passing a recycle stream through a fluidized bed in a gas phase fluidized bed reactor, wherein the recycle stream comprises a low molecular weight dew point increasing component and a high molecular weight component, polymerizing an alpha-olefin monomer in the presence of a catalyst, and controlling an amount of the low molecular weight dew point increasing component in the recycle stream such that a dew point approach temperature of the recycle stream is less than the dew point approach temperature when operating with the higher molecular weight dew point increasing component alone.
