More Information
Summary:The deactivation of Ziegler-Natta catalyst and organometallic cocatalyst residues present in the olefin polymer resins produced by the fluidized bed polymerization process is accomplished in a purge vessel by contacting the olefin polymer resin with an inert purge gas containing water the latter being present in said inert purge gas in an amount to establish and maintain a moisture front region in the resin bed of said purge vessel as to create a region above said moisture front substantially free of water and wherein deactivation of said catalyst and cocatalyst are effected in said moisture front region.
