ABSTRACT:
Hydrogenation products of olefinically unsaturated polymers having nitrile groups prepared in the presence of ruthenium catalysts in a solvent comprising a low-molecular ketone and a secondary or tertiary C.sub.3 -C.sub.6 -alcohol by hydrogenation, can be processed to vulcanizates with improved compression set values.
