Abstract
Styrene was polymerized using a series of methylaluminoxane-activated bis(phenolato)titanium complexes of the type {(OC6H2-4-Me-6-Bu-t)(2)Z} TiX2 (X = Cl, (OPr)-Pr-i, eta(5)-C5Me5) to give syndiotactic polystyre ne. Catalyst activity was found to depend on the nature of the bridgin g group Z, where Z = CH2, CH2CH2, S, S=O. Activity was found to be hig hest for Z = S.
