Abstract:
Catalyst compositions based on Ruthenium- or Osmium-based complex catalysts and specific co-catalysts are provided for selectively hydrogenating nitrile rubbers in the presence of such catalyst compositions.

Claim (Index 6):
The process for hydrogenating nitrile rubber according to  claim 1 , further comprising, prior to hydrogenation, subjecting the nitrite rubber to a molecular weight degradation in a metathesis reaction comprising contacting the nitrile rubber in the absence or presence of a co-olefin with a complex catalyst based on ruthenium or osmium as central metal and bearing at least one ligand bound to the ruthenium or osmium central metal in a carbene-like fashion, then\n c) contacting the complex catalyst which is present in the reaction mixture obtained after the metathesis reaction with at least one co-catalyst having at least one vinyl group in a molar ratio of the complex catalyst to the co-catalyst of 1:(20-550) to form a catalyst composition, and thereafter d) hydrogenating the nitrite rubber in the presence of the catalyst composition.
