Ruthenium-based catalyst for the preparation of high performance hydrogenated nitrile-butadiene rubber by controlled latex hydrogenation
The ruthenium-based catalyst [1,3-bis(trimethylphenyl)-2-imidazolinylidene]·dichloro·(o-methoxybenzylidene) ruthenium was synthesized and used to prepare the latex of hydrogenated nitrile-butadiene rubber(HNBR). The selectivity and reactivity of catalyst, the gel content, curing characteristics, ph...
