Abstract:
This invention relates to novel catalyst compositions based on Ruthenium- or Osmium-based complex catalysts of the Grubbs-Hoveyda, Grela or Zhan type and specific co-catalysts comprising at least one vinyl group, pref. ethyl vinyl ether, and to a process for selectively hydrogenating nitrile rubbers in the presence of such catalyst compositions, preferably with a preceding metathesis step using the same complex catalyst as in the hydrogenation step.

Claim (Index 8):
The process according to  claim 1 , further comprising:\n a) preparing the catalyst composition according to  claim 1  by contacting the complex catalyst according to  claim 1  with the at least one co-catalyst according to  claim 1  in a molar ratio of the complex catalyst to the co-catalyst of 1:30 to 1:100, and thereafter b) hydrogenating nitrile rubber in the presence of the catalyst composition formed in step a).
