Abstract
Polymerization processes are described herein. The polymerization processes generally include introducing a catalyst system to a reaction zone, introducing an olefin monomer to the reaction zone, contacting the olefin monomer with the catalyst system to form a polyolefin and contacting the polyolefin with a quench agent, wherein the quench agent is at least partially soluble in the olefin monomer.
