Syndiotactic polymerization of styrene in the presence of CpTiCl2(OC6H4X)/MAO catalytic systems

CpTiCl2(OC6H4X‐p) complexes (where X =CH3, Cl, NO2,; Cp = cyclopentadienyl) activated with methylaluminoxane (MAO) were used in syndiotactic polymerization of styrene. High activity and selectivity for all catalysts were found. The styrene conversion and reaction selectivity depend on the catalyst...

Zusammenfassung:	CpTiCl2(OC6H4X‐p) complexes (where X =CH3, Cl, NO2,; Cp = cyclopentadienyl) activated with methylaluminoxane (MAO) were used in syndiotactic polymerization of styrene. High activity and selectivity for all catalysts were found. The styrene conversion and reaction selectivity depend on the catalyst ageing time and temperature, polymerization temperature and the nature of the substituent in the phenoxy ring.
