摘要:
A process of degrading nitrile rubbers comprises subjecting them to a metathesis reaction in the presence of specific catalysts with increased activity.
摘要:
A novel process for the degradation of nitrile rubber by metathesis using ruthenium- or osmium-based catalysts which have both a substituted or unsubstituted imidazolidine ligand and a carbene ligand bearing a phosphonium radical is provided.
摘要:
Provided are new functionalized nitrile rubbers, which may optionally also be in partially or wholly hydrogenated form, and also a process for preparing them by metathesis of nitrile rubbers in the presence of a metathesis catalyst and at least one functionalized allyl compound. The new functionalized nitrile rubbers are suitable for producing vulcanizable mixtures and allow the production of vulcanizates having very stable networks. Also made possible, in particular, is the synthesis of block copolymers.
摘要:
A novel process for the metathetic degradation of nitrile rubbers is provided which uses specific transition metal complex catalysts showing an increased activity.
摘要:
Novel catalyst systems for metathesis reactions, in particular for the metathesis of nitrile rubber, which contain a specific salt additive in addition to the metathesis catalyst are provided.
