    摘要: Polymerisates of ethylene, which can be obtained by polymerisation of ethylene and, optionally, other comonomers in the presence of a catalyst system containing as active constituents I) a Phillips catalyst; II) a solid distinguishable from I) and containing a constituent which is derived from the metallocene complexes of general formula (A), in which the substituents and indexes have the following meaning: R?1 to R10¿ is hydrogen, C¿1?-to C10-alkyl, 5- to 7-membered cycloalkyl, which may, in turn, have C1-to C6-alkyl groups as substituents, C6-to C15-aryl or arylalkyl and wherein optionally two adjacent residues may also be cyclic groups having 4 to 15 C-atoms, or Si(R?11)¿3, where R11 is C1- to C10-alkyl, C6- to C15-aryl or C3- to C10-cycloalkyl, or wherein the residues R?4 and R9¿ form together a grouping -Y[(R12R13]m where Y is silicon, germanium, tin or carbon; R12, R13 is hydrogen, C¿1?- to C10-alkyl, C3- to C10-cycloalkyl or C6- to C15-aryl; M is a metal of IV to VII subgroup or a metal of the lanthanide series; Z?1, Z2¿ is fluorine, chlorine, bromine, iodine, hydrogen, C¿1?- to C20-alkyl or aryl residue, -OR?14, -OOCR14¿, (a), (b) or (c), where R14 is hydrogen or C¿1?- to C20-alkyl; R?15 is C¿1- to C20-alkyl; m is 1, 2, 3 or 4; n is 0, 1 or 2; r is 0, 1 or 2, wherein the sum n+r is also 0, 1 or 2, and optionally III) an organometallic compound constituent selected from the groups IA, IIA, IIB and IIIA of the periodic system.
