Abstract: A process for the preparation of polymers of C2- to C10-alk-1-enes at pressures of from 0.5 to 3000 bar and temperatures of from -50 to 300 DEG C using a catalyst system, characterised in that the catalyst systems used are those containing, as active constituents, a) metallocene complexes of the formula I b) an open-chain or cyclic aluminoxane compound. lk

Abstract: Metallocene complexes of the general formula I in which the substituents have the following meaning: M is titanium, zirconium, hafnium, vanadium, niobium or tantalum, X is fluorine, chlorine, bromine, iodine, hydrogen, C1- to C10-alkyl, C6- to C15-aryl or -OR , where R is C1- to C10-alkyl, C6- to C15-aryl, alkylaryl, arylalkyl, fluoroalkyl or fluoroaryl in each case having 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical, R to R are hydrogen, C1- to C10-alkyl, 5- to 7-membered cycloalkyl which for its part can carry C1- to C10-alkyls as substituents, C6- to C15-aryl or arylalkyl, where, if appropriate, two adjacent radicals together can also stand for cyclic groups having 4 to 15 C atoms, or Si(R )3 where R is C1- to C10-alkyl, C6- to C15-aryl or C3- to C10-cycloalkyl, Z is silicon, germanium, tin or carbon, Y and Y are where R to R are hydrogen, C1- to C10-alkyl, 5- to 7-membered cycloalkyl which for its part can carry C1- to C10-alkyls as substituents, C6- to C15-aryl or arylalkyl, where, if appropriate, two adjacent radicals together can also stand for cyclic groups having 4 to 15 C atoms, or Si(R )3, where R is C1- to C10-alkyl, C6- to C15-aryl or C3- to C10-cycloalkyl, and u, v and w are integers from 0 to 7, with the proviso that the sum u + v + w >/= 2, and cyclopentadienyl compounds of the general formula II and cyclopentadienyl compounds of the general formula III as intermediates.t
