Patent ID: 7858736

Claim:
A polymer recovery process comprising contacting a polymerization reactor effluent with a fluorinated hydrocarbon after the polymerization reaction has stopped and thereafter recovering olefin polymer, where the fluorinated hydrocarbon is present at 10 volume % to 80 volume % based upon the volume of the effluent and the fluorinated hydrocarbon, and where the polymerization is a continuous polymerization of at least 75 mole % of hydrocarbon monomers, based upon the total moles of monomer present in the reactor, and wherein the fluorinated hydrocarbon comprises a hydrofluorocarbon, provided that when the polymerization process is conducted in the presence of fluorinated hydrocarbon, additional fluorinated hydrocarbon (which may be the same or different from the first fluorinated hydrocarbon) is added to the polymerization reactor effluent after the polymerization reaction has stopped.
