Novel Titanium Catalysts Bearing an [O, N, S] Tridentate Ligand for Ethylene Homo- and Copolymerization†

By a sidearm approach, a series of titanium complexes bearing an [O, N, S] tridentate ligand have been synthesized and proven to be highly active for ethylene polymerization. The complexes also show excellent ability to copolymerize ethylene with hex-1-ene and norbornene. The effects of the different sidearms on the catalytic behavior of the complexes were studied in detail.
