摘要： Catalysts for the polymerization of olefins are disclosed, which comprise the product obtained by contacting: (A) a bridged and/or substituted cyclopentadienyl compound of titanium, zirconium or hafnium; (B) an organometallic aluminium compound of the formula: Al(CH2—CR4R5—CR6R7R8)wR9qHz wherein R4 is a C1-C10 alkyl, alkenyl, or arylalkyl group; R5 is hydrogen or a C1-C10 alkyl, alkenyl, or arylalkyl group; R6 and R7 are C1-C10 alkyl, alkenyl, aryl, arylalkyl or alkylaryl groups; R8 is hydrogen or a C1-C10 alkyl, alkenyl, aryl, arylalkyl or alkylaryl group; R9 is a C1-C10 alkyl, alkenyl, or arylalkyl group, a carbon atom in the compound of formula (II) being optionally replaced by a Si or Ge atom; w is 1-3, z is 0 or 1, q=3−w−z, and (C) water; the molar ratio (B)/(C) being comprised between 1:1 and 100:1. These catalysts show an improved activity with respect to known catalysts, wherein different aluminium compounds are used.
