The present invention relates to a titanocene complex and a catalyst comprising
the same and an alkylaluminoxane for preparing syndiotactic polystyrene. The catalyst
is applicable to the industrial production of the syndiotactic polymerization of
styrene. The titanocene complex has a general formula of R1Ti(OR2R3)3,
where R1 is Cp or Cp containing 1-5 C1-4 alkyls, R2
is an aryl containing 6-12 carbon atoms, R3 is a halogen, OR2R3
is a halogenated aryloxy ligand.
