    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.

    Abstract: Polymers of vinylaromatic cpds. are prepd. at 0-150 deg.C, in presence of catalysts contg. as active components (A) cpds. of formula XM(Z )z1(Z )z2(Z )z3 (I) and (B) (i) open-chain or cyclic alumoxane cpds. of formula (III) or (IV), or (ii) cpds. forming metallocene ions, comprising strong neutral Lewis acids, ionic cpds. with Lewis acid cations or ionic cpds. with a Bronsted acid as cation. In the formulae, X = 1-10C alkyl or alkoxy, 5-7 member cycloalkyl, 6-15C aryl or formula (II) (where R -R = H, 1-10C alkyl (opt. with 1-5 halogen substits.), 5-7 member cycloalkyl (opt. with 1-6C alkyl substits.), 6-15C aryl or arylalkyl where 2 vicinal gps. may together form 4-15C cyclic gps., or halogen, 1-10C alkoxy, NR R or Si(R )3 (where R , R = H, 1-10C alkyl, 6-15C aryl or 3-10C cycloalkyl); M = metal of the IInd - VIIIth Sub-gps.; Z -Z = polymers of vinylaromatic cpds., dienes, and/or acrylates; z1, z2, z3 = 0-3; z1 + z2 + z3 = 1-3; R = 1-4C alkyl; m = 5-30.
