Abstract
The use of induced condensing agent (ICA) in fluidized bed gas phase reactor systems enables higher production rates but can affect the resulting polyolefins melt index. The effect the increased ICA concentration may have on a melt index may be counteracted, if necessary, by altering the concentration of olefin monomer within the reactor system.
