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 fluorinated hydrocarbon and recovering the polymer. The processes provided enable polymerization processes to be practiced with minimal fouling in the reaction system, and allows for the recovery of the fluorinated hydrocarbon 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 propylene based polymers using Ziegler Natta catalyst systems.

摘要: This invention is directed to a polymerization process that is carried out at relatively high productivity levels and with relatively low fouling. The process includes mixing together a catalyst system, at least one monomer and a hydrofluorocarbon to produce the polymer. The reaction is carried out such that little to no chlorine containing hydrocarbons are present.
