The present invention relates to hydrogenation catalysts composed of metal-based complexes, preferably (fused) iminovinyloxy Ru species, such as those known under the trade names Umicore M41 or Umicore M42, in combination with specific cocatalysts such as ethylvinyl A novel hydrogenation catalyst composition obtainable by ether (EVE) reaction, and relates to a method for selectively hydrogenating nitrile rubber (optionally prior to molecular weight metathesis reduction) in the presence of this novel hydrogenation catalyst composition )Methods. |
