HYDROGENATION OF UNSATURATED POLYMERS USING DIVALENT NON-AROMATIC ANIONIC DIENYL-CONTAINING GROUP IV METAL CATALYSTS

摘要

Organic compounds are hydrogenated in the presence of certain mono- or bis(pentadienyl) divalent Group IV metal complexes. These titanium complexes are effective hydrogenation catalysts for polymers containing ethylenic unsaturation. They further provide for selective hydrogenation of ethylenic unsaturation sites in the presence of aromatic groups.
