METHODS FOR IMPROVING HEAT TRANSFER IN POLYMERIZATION PROCESSES

摘要

Methods for improving heat transfer in polymerization processes are described herein. The methods generally include contacting olefin monomer with a catalyst system within a reaction zone to form particles having a first average particle size and altering the reaction zone to improve heat transfer and form polymer particles having a second average particle size. For example, the second average particle size may be larger than the first average particle size and the second particle size results in improved heat transfer over the first particle size.
