Patent ID: 8148450

Claim:
A process to produce an essentially homogeneous single liquid phase hydrocarbon-rubber cement from a polymer slurry comprising a hydrocarbon-rubber, a diluent, and unreacted monomer(s), said process comprising: (a) following polymerization of the hydrocarbon-rubber, contacting said polymer slurry with a hydrocarbon solvent; and (b) removing said diluent and said hydrocarbon solvent in amounts not sufficiently more than is necessary to produce said essentially homogeneous single liquid phase hydrocarbon-rubber cement wherein the mass fraction of monomer(s) in the hydrocarbon-rubber cement, based on the total amount of hydrocarbon-rubber present in the hydrocarbon-rubber cement, is less than the mass fraction of monomer(s) in the hydrocarbon-rubber slurry, based on the total amount of hydrocarbon-rubber present in the hydrocarbon-rubber slurry, wherein said diluent comprises a hydrofluorocarbon.
