Title:
ニトリルゴムをメタセシスにより分解するための触媒の使用
Document Type and Number:
Japanese Patent JP5047564
Kind Code:
B2
Abstract:
Degradation of nitrile rubbers by metathesis involves: subjecting the nitrile rubber to a metathesis reaction in the presence of a ruthenium- or osmium-based catalyst containing an imidazolidine ligand and a carbene ligand containing a phosphonium radical. Degradation of nitrile rubbers by metathesis involves: subjecting the 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 : optionally substituted imidazolidine radical; A : an anion. [Image].
