Abstract
A series of 32 complexes of 1,1-bis-(benzoxazolyl)methane, 1,2-bis-(benzoxazolyl)
ethane, 1,2-bis-(benzoxazolyl)benzene and 2,6-bis-benzoxazolyl)pyridine compounds with Ti(IV)
chloride, Zr(IV) chloride and V(III) chloride was synthesized and characterized. After activation
with methylaluminoxane (MAO), these complexes proved as good ethylene polymerization
catalysts. Surprisingly the activities of the corresponding catalysts depend considerably on the
nature of the bridging unit of the ligand. Structure property relationship studies revealed that
titanium complex 16 with a methylene bridge gave the best performance
