NOVEL CATALYST FOR HYDROGENATION OF LIVING POLYMER AND ITS USE FOR HYDROGENATION

摘要

The present invention relates to a catalyst compound for living polymer hydrogenation represented by the following general formula (I) used for the hydrogenation reaction of a living polymer comprising copolymerization of a conjugated double bond monomer and an aromatic vinyl monomer.;Wherein Cp represents a cyclopentadienyl (C ₅ H _5- ) group, X ₁ , X ₂ are each a halogen atom such as chlorine or bromine, Y is a carbon or nitrogen atom, and R ₁ , R ₂ , R ₃ is hydrogen or a lower alkyl group having 1 to 4 carbon atoms, respectively.
