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

Abstract: A process for the preparation of multiphase homopolymers or copolymers of C2-C10-alk-1-enes, characterised in that the polymerisation is carried out in one reaction zone in the presence of two different catalyst systems, where one of the catalyst systems contains, as active constituents, a metallocene complex of the formula (I) or (II) in which M is a metal from group IVb, Vb or VIb of the Periodic Table, R and R are identical or different and are a hydrogen atom, a C1-C10-alkyl group, a C1-C10-alkoxy group, a C6-C10-aryl group, a C6-C10-aryloxy group, a C2-C10-alkenyl group, a C7-C40-arylalkyl group, a C7-C40-alkylaryl group, a C8-C40 arylalkenyl group or a halogen atom, R and R are identical or different and are a hydrogen atom, a halogen atom, a C1-C10-alkyl group, which may be halogenated, a C6-C10-aryl group, an -NR 2, -SR , -OSiR 3, - SiR 3 or -PR 2 radical, in which R is a halogen atom, a C1-C10-alkyl group or a C6-C10-aryl group, and R and R are identical or different and are as defined for R and R with the proviso that R and R are not hydrogen.
