摘要: This invention relates to a process to increase the amount of polymer solute in a polymerization medium or effluent comprising introducing a fluorocarbon into the polymerization medium or effluent in an amount effective to increase the amount of polymer solute in the polymerization medium or effluent by at least 3% without causing precipitation of polymer solute from the polymerization medium or effluent, as compared to the same polymerization medium or effluent without the fluorocarbon present. This invention also relates to a process to reduce the viscosity of a polymerization medium or effluent comprising introducing a fluorocarbon into the polymerization medium or effluent in an amount effective to reduce the viscosity of the polymerization medium or effluent by at least 3% without causing precipitation of polymer solute from the polymerization medium or effluent, as compared to the same polymerization medium or effluent without the fluorocarbon present.

摘要: This invention is directed to processes of making polymer in the presence of a hydrofluorocarbon or perfluorocarbon and recovering the polymer. The processes provided enable polymerization processes to be practiced with minimal fouling in the reaction system, and to the recovery of the hydrofluorocarbon and other hydrocarbons such as hydrocarbons for reuse in the process or hydrocarbon by-products from the polymerization process. The invention is particularly beneficial in the production of ethylene based polymers using Ziegler Natta catalyst systems.
