Preparation of new catalysts for selective hydrogenation of double bonds of olefinic living polymers and hydrogenation using the same

摘要

The present invention relates to the preparation of a homogeneous, homogeneous organotitanium catalyst having high activity for selective hydrogenation of a living polymer having an olefinic double bond and a hydrogenation reaction using the catalyst. More particularly, the present invention relates to a process for preparing an organic tartan-based hydrogenation catalyst having a plurality of catalytic active sites prepared by reacting a macromolecule having a plurality of alkoxy groups having a steric hindrance in one molecule with a monocyclopentadienyltitanium trihalogen compound, And a method for selectively hydrogenating a living polymer having an olefinic double bond with high yield, high selectivity and high reproducibility by performing a hydrogenation reaction using the catalyst.
