Claim Text:
1. A vulcanizable composition comprising: a) 100 parts by weight, based on 100 parts by weight of rubber, of one or more hydrogenated nitrite rubbers having a Mooney viscosity (ML 1+4 @ 100° C.) of 10 to 120 MU, wherein the one or more hydrogenated nitrile rubbers are co- or terpolymers based on at least one conjugated diene and at least one α,β-unsaturated nitrile monomer, in which the degree of hydrogenation of the diene units incorporated into the sot mar is 95 to 100%; b) 1 to 100 parts by weight, based on 100 parts by weight of rubber, one or more unsaturated carboxylic acids and/or one or more salts thereof; c) 0.2 to 8 parts by weight, based on 100 parts by weight of rubber, at least one peroxide; and d) at least one microgel having a glass transition temperature less than or equal to −20° C.
