    Abstract: The invention relates to a method for producing polymers based on monomers with a C=C double bond by homopolymerization or copolymerization of said monomers in the presence of a catalyst system consisting of a metallocene complex A) and a compound forming a metallocenium ions B) and optionally a metal organic compound of the I, II or III main group of the periodic table of elements C). The invention is characterized in that a compound of general formula (I) is used as a metallocene complex A), wherein the substituents and indices have the following meaning: R to R = hydrogen, C1-C10-alkyl, 5 to 7 membered cycloalkyl, which in turn can have C1-C6-alkyl groups as substituents, C6-C15-aryl or arylalkyl and wherein optionally two neighboring radicals R to R can also stand together for cyclic groups having from 4 to 15 C atoms, or Si(R )3, R standing for C1-C10-alkyl, C6-C15-aryl or C3-C10-cycloalkyl, M = a metal of the III to VI sub-group of the periodic table of elements or a metal of the lanthanide series, X is the same or different and stands for hydrogen, halogen C1-C10-alkyl, C6-C15-aryl, C1-C10-alkoxy or C6-C15-aryloxy, and n = 1, 2, 3, 4 or 5, whereby n corresponds to the valence of M minus 1.
