(57) ABSTRACT

. . . . The present 1nvent1on prov1des a novel process for prepanng

hydrogenated nitrile rubbers comprising subjecting nitrile

rubbers in a spinning disk reactor to hydrogenation. The presentprocessislessdemandingWithregardtoitsreaction conditions, like e.g. the hydrogen pressure to be applied, compared to knoWn processes and signi?cantly reduces the costofthehydrogenationprocessandinparticulartheequip 11161110051
