Monocyclopendienyltitanium trichloride (CpTiCl 3 ) was supported on polymer carriers with different hydroxyl contents, and the supported catalysts were used for styrene polymerization. The supported catalysts exhibited high activity even at low Al/Ti ratios and increased the molecular weight of the
Styrene was polymerized using a series of methylaluminoxane-activated bis(pheno1ato)titanium complexes of the type , O'Pr, q5-CsMes) to give syndiotactic polystyrene. Catalyst activity was found to depend on the nature of the bridging group Z, where Z = CH2, CH2CH2, S, S=O.
