AbstractTwo multi-nuclear titanium complexes [Ti(eta(5)-Cp-*) Cl(mu-O)](3) ( 1) and [(eta(5)-(CpTiCl)-Ti-*)(mu-O)(2)(eta(5)-(CpTi)-Ti-*)(2)(mu-O)(mu-O)(2)](2)Ti (Cp-* = C5Me5) ( 2) have been investigated as the precatalysts for syndiospecific polymerization of styrene. In the presence of modified methylaluminoxane ( MMAO) as a cocatalyst, complexes 1 and 2 display much higher catalytic activities towards styrene polymerization, and produce the higher molecular weight polystyrenes with higher syndiotacticities and melting temperatures ( T-m) than the mother complex (CpTiCl3)-Ti-* does when the polymerization temperature is above 70 degrees C and the Al/Ti molar ratio is in the low range especially.
