ABSTRACT:
Statistical copolymers of from 85 to 52% by weight of a conjugated diene, from 15 to 48% by weight of at least one unsaturated nitrile and from 0 to 10% by weight of further monomers, copolymerizable with diene and nitrile, which have a molecular weight M.sub.n of from 0.5 to 30 kg/mol and a degree of hydrogenation of the double bonds of greater than 80%, give nitrile rubbers, which are mixed and colvulcanized with these copolymers, an increased ozone resistance.
