1. A process for the production of a hydrogenated nitrile rubber, the process comprising simultaneously hydrogenating and metathesizing nitrite rubber in the presence of hydrogen, at least one catalyst, and optionally at least one co-olefin, wherein each at least one catalyst is capable of catalyzing both the hydrogenating and metathesizing, and catalyzes the hydrogenating and metathesizing of the nitrite rubber, and each at least one catalyst is selected from the group consisting of compounds of general formulae (I), (II) or (Ill), where M is ruthenium or osmium, X1 and X2 are identical or different anionic ligands, Z1 and Z2 are identical or different neutral electron donor ligands, R3 and R4 are each independently hydrogen or a substituent selected from the group consisting of alkyl, cycloalkyl, alkenyl, alkynyl, aryl, carboxylate, alkoxy, alkenyloxy, alkynyloxy, aryloxy, alkoxycarbonyl, alkylamino, alkylthio, arylthio, alkylsulphonyl and alkylsulphinyl radical, each of which may optionally be substituted by one or more alkyl, halogen, alkoxy, aryl or heteroaryl radicals, and L is a ligand. |
