The present invention relates to a process to remove residue from partially hydrogenated nitrile rubber. The process is undertaken by mixing and kneading the rubber in the presence of an extractant fluid. The extractant fluid is a solvent for the residue but is not a solvent for the rubber. At the conclusion of the process, the rubber is separated from the residue-containing extractant fluid.
