    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 for making polymer in the presence of a hydrofluorocarbon, and for the recovery of polymer substantially free of dissolved hydrocarbons and hydrofluorocarbons. The processes provided enables polymerization processes to be practiced with minimal fouling in the reaction system, and with the recovery of the hydrofluorocarbon and monomers for reuse in the reactor. The process of the invention utilizes a reactor system, a recovery system and a flare system that minimize environmental emissions of hydrocarbons, hydrofluorocarbons and associated decomposition products.
