Abstract

A series of titanium complexes bearing ansa-(fluorenyl)(amido) ligands with cyclohexylamido, isopropylamido, and isobutylamido groups were synthesized and their catalytic behaviors for the copolymerization of ethylene with isobutylene were compared with those with cyclododecylamido and tert-butylamido groups. The effects of cocatalyst on the ethylene-isobutylene copolymerization by a titanium complex having ansa-(fluorenyl)(cyclododecylamido) ligand were examined. The catalytic activity of the titanium complex for ethylene-limonene copolymerization was also further investigated.
