A monocyclopentadienyl complex comprising cyclopentadienyl containing at least one bridged donor and at least one arylalkyl group is new. A monocyclopentadienyl complex comprises cyclopentadienyl containing at least one bridged donor and at least one arylalkyl group; and having the structural feature of formula (I) is new. Cp-Y mM (I) Cp : cyclopentadienyl system having an arylalkyl substituent; Y : at least one charge donor containing at leas tone atom of group 15 or 16 of the periodic table; and M : Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, an element of group 3 of the periodic table or lanthanide; and m : 1-3. Independent claims are also included for: (1) a catalyst system comprising (I), optionally an organic or inorganic support, optionally at least one activating compound, optionally further catalysts suitable for olefin polymerization and optionally at least one metal compound containing a metal of group 1, 2 or 13 of the periodic table; and (2) a prepolymerized catalyst system comprising the catalyst system and at least one linear 2-10C 1-alkene polymerized onto it in a mass ratio of 1:0.1-1:1000 based on the catalyst system. |
