Synthesis, Characterization, and Ethylene (Co)Polymerization Behavior of Trichlorotitanium 2-(1-(Arylimino)propyl)quinolin-8-olates

A series of trichlorotitanium complexes containing 2-(1-(arylimino)propyl)quinolin-8-olates was synthesized by stoichiometric reaction of titanium tetrachloride with the corresponding potassium 2-(1-(arylimino) propyl) quinolin-8-olates and was fully characterized by elemental analysis, nuclear magnetic resonance spectroscopy, and by single-crystal X-ray diffraction study of representative complexes. All titanium complexes, when activated with methylaluminoxane, exhibited high catalytic activity toward ethylene polymerization [up to 1.15 x 10(6) g mol(-1) (Ti) h(-1)] and ethylene/alpha-olefin copolymerization [up to 1.54 x 10(6) g mol(-1) (Ti) h(-1)]. The incorporation of comonomer was confirmed to amount up to 2.82 mol % of 1-hexene or 1.94 mol % of 1-octene, respectively. (C) 2011 Wiley Periodicals, Inc.
