摘要：Degradation of nitrile rubbers by metathesis involves: subjecting the nitrilerubber to a metathesis reaction in the presence of a ruthenium- or osmium-basedcatalyst containing an imidazolidine ligand and a carbene ligand containing a

phosphonium radical. Degradation of nitrile rubbers by metathesis involves: subjectingthe nitrile rubber to a metathesis reaction in the presence of a catalyst of formula (I). M :ruthenium or osmium; X 1 and X 2anionic ligands; R 1-R 3organic radicals; Im : optionallysubstituted imidazolidine radical; A : an anion. [Image].
