    Abstract: The invention relates to a catalyst system for polymerizing C2 to C12-alk-1-enes containing; A) one organic or inorganic support; B) at least one metallocene complex; C) oligomeric aluminum oxide compounds; D) at least one boron compound of general formula (I) or a cyclic boron compound of general formula (II) or mixtures from boron compounds (I) and (II). The substituents in said formulas (I) and (II) have the following significance: R1 to R4 a C1 to C20 alkyl group which can be substituted by halogen atoms, C6 to C15 aryl groups and/or C1 to C10 alkoxy groups; a C4 to C7 cyclo-alkyl group which can be substituted by halogen atoms, C1 to C10 alkyl groups and/or C1 to C10 alkoxy groups; a C1 to C10 alkoxy or alkyl sulfide group which can be substituted by halogen atoms, C1 to C10 alkyl groups and/or C6 to C15 aryl groups; a C6 to C15 aryl group which can be substituted by halogen atoms, C1 to C10 alkyl groups, C1 to C10 halogen alkyl groups, C4 to C10 cyclo-alkyl groups, C6 to C15 aryl groups, C1 to C10 alkenyl groups, amino groups, monoor dialkyl amino groups, nitro-groups, formyl groups, acetamido-groups and/or C1 to C10 alkoxy groups, or a saturated or unsaturated C3 to C15 heterocycle containing one to three oxygen, sulfur and/or nitrogen atoms in the ring system and which can be substituted by halogen atoms, C6 to C15 aryl groups, additional C3 to C15 heterocycles and/or C1 to C10 alkyl groups; R1 to R4 are also defined as above and also carry one to three additional B(OR')(OR'') groupings or if R1 to R4 contain an aromatic ring, said ring is part of a metallocene system; R' and R'' are the same or different and each signify hydrogen or a C1 to C10 alkyl group.

    Abstract: Catalyst systems for polymerising C2 to C10 alkenes, containing as active components metallocene complexes of metals of sub-groups IV and V of the periodic system, an oligomeric aluminium oxide compound and a cyclic boron compound of general formula (IV) in which R to R are C1 to C10 alkyl groups which may be substituted singly to triply by halogen atoms, C6 to C15 aryl groups or C1 to C10 alkoxy groups; C4 to C7 cycloalkyl groups which may be substituted singly to triply by halogen atoms, C1 to C10 alkyl groups or C1 to C10 alkoxy groups; C1 to C10 alkoxy groups which may be substituted singly to triply by halogen atoms, C1 to C10 alkyl groups or C6 to C15 aryl groups; or C6 to C15 aryl groups which may be substituted singly to fivefold by halogen atoms, C1 to C10 alkyl groups or C1 to C10 alkoxy groups.
