Abstract
AbstractMonocyclopentadienyl titanium complexes of the type Cp*TiX2 L (Cp*=C5 Me5, 1: L=C6 F5 S, X=OMe; 2: L=C6 F5 S, X=Cl; 3: L=2, 6-Me2-C6 H3 S, X=OMe) have been synthesized with high yields. These complexes are used as the catalysts for the syndiospecific polymerization of styrene. High catalytic activity is observed, and a polymer with high molecular weight and narrow molecular weight distribution is obtained. It is concluded that not only the sulfur-containing donor ligand but also the anion ligand strongly affects the polymerization activity and the molecular weight of the resultant polymer.
