ABSTRACT:
An improved process is provided for the catalytic hydrogenation of nitrile rubber using a ruthenium catalyst wherein the improvement is that the nitrile rubber is provided as an aqueous emulsion and a solvent and a selected inorganic additive are present during the hydrogenation, whereby the molecular weight increase in the hydrogenation process is minimized and controlled.
