25 Claims

1. A solution olefin polymerization process, in which the olefin polymer is present as a solute in a polymerization medium, comprising introducing a fluorinated hydrocarbon into the polymerization medium in an amount effective to increase the amount of polymer solute in the polymerization medium by at least 3%, as compared to the same polymerization medium without the fluorinated hydrocarbon present, without causing precipitation of polymer solute from the polymerization medium, where the fluorinated hydrocarbon is not a perfluorinated C4 to C10 alkane, where the olefin polymer is at least 75 mole % hydrocarbon monomer and the monomers to be polymerized are not fluoromonomers.
