Partially hydrogenated nitrile rubbers (I) with a hydrogenation degree of 50-97%, and a quotient of the solution viscosity divided by the weight average molecular weight of 4 x 10 -> 3>to 50 x 10 -> 3>Pa.s.mol/kg, is claimed. Independent claims are included for: (1) vulcanizable mixture containing (I) at least one peroxide crosslinking system; (2) producing vulcanizates comprising crosslinking the vulcanizable mixture by increasing the temperature, in a shaping process, preferably under the use of injection molding; (3) the preparing of (I) comprising subjecting partially hydrogenated nitrile rubbers having a hydrogenation degree of 50-97%, to a metathesis reaction in the presence of a complex catalyst based on a metal of the 6th or 8th subgroups of the periodic table, preferably molybdenum, osmium or ruthenium, that exhibit at least one carbene type ligand bonded to the metal, where the metathesis is carried out substantially free of 2-16C-olefins; and (4) vulcanizates obtained by the above process. |
