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 12):
The process for hydrogenating nitrile rubber according to  claim 9 , wherein the complex catalyst is of general formula (A) and one or both of the ligands L have a structure according to general formulae (IIa)-(IId), wherein the meaning of L can be identical or different in case both ligands L have a structure according to (IIa) to (IId), where\n R 8 , R 9 , R 10  and R 11  are identical or different and represent hydrogen, straight-chain or branched C 1 -C 30 -alkyl, C 3 -C 20 -cycloalkyl, C 2 -C 20 -alkenyl, C 2 -C 20 -alkynyl, C 6 -C 24 -aryl, C 6 -C 24 -aryl, C 7 -C 25 -alkaryl, C 2 -C 20  heteroaryl, C 2 -C 20  heterocyclyl, C 1 -C 30 -alkoxy, C 2 -C 3 -alkenyloxy, C 2 -C 20 -alkynyloxy, C 6 -C 20 -aryloxy, C 2 -C 20 -alkoxycarbonyl, C 3 -C 20 -alkylthio, C 6 -C 20 -arylthio, \u2014Si(R) 3 , \u2014O\u2014Si(R) 3 , \u2014O\u2014C(\u2550O)R, C(\u2550O)R, \u2014C(\u2550O)N(R) 2 , \u2014NR\u2014C(\u2550O)\u2014N(R) 2 , \u2014SO 2 N(R) 2 \u2014S(\u2550O)R, \u2014S(\u2550O) 2 R, \u2014O\u2014S(\u2550O) 2 R, halogen, nitro or cyano, wherein in all above occurrences relating to the meanings of R 8 , R 9 , R 10  and R 11  the group R is identical or different and represents hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, aryl or heteroaryl, and \n R 15 , R 16  and R 17  are identical or different and may represent alkyl, cycloalkyl, alkoxy, aryl, aryloxy, or a heterocyclic group.
