Method for hydrogenation of polymer |
摘要 |
Selective hydrogenation of unsaturated double bonds in conjugated diene units of a conjugated diene polymer resulting from polymerization of copolymerization of a conjugated diene is effected by a method which comprises hydrogenating the conjugated diene polymer in an inert solvent in the presence of: (A) at least one bis-(cyclopentadienyl) titanium compound or (B) at least one hydrocarbon lithium compound containing at least one lithium atom in addition to (A) the aforementioned at least one bis-(cyclopentadienyl) titanium compound as a catalyst (providing that the presence of both the two components, (A) and (B), is essential where the conjugated diene polymer under treatment is other than a living polymer containing a lithium atom in the polymer chain thereof).
