    摘要: Nitrile group-containing polymers are hydrogenated in a homogeneous phase with preservation of the nitrile groups in a low molecular weight ketone as a solvent and with a compound corresponding to formulaRuX[(L.sub.1)(L.sub.2).sub.n ]as a catalyst, whereinX represents hydrogen, halogenL.sub.1 represents hydrogen, halogen, optionally substituted cyclopentadienyl,L.sub.2 represents a phosphane, bisphosphane or arsane andn is 1, 2 or 3 and[(L.sub.1)(L.sub.2).sub.n ] represents a cyclopentadienyl bisphosphane.
