Abstract:
Provided for herein is a process for separating a hydrocarbon-rubber from a hydrofluorocarbon diluent comprising contacting a polymer slurry comprising the hydrocarbon-rubber dispersed within the hydrofluorocarbon diluent with a hydrocarbon solvent capable of dissolving the hydrocarbon-rubber, to produce a first liquid phase and a second liquid phase, and separating the first liquid phase from the second liquid phase.
