    Abstract: The invention relates to complex compounds of general formula (I) (a to d), wherein M is an element of groups 6 to 10 of the periodic table of the elements, preferably Ni. The invention also relates to a method for the production and of said compounds and to their use in the polymerization and copolymerization of olefins, for example in suspension polymerization methods, gaseous phase polymerization methods, mass polymerization methods or emulsion polymerization methods.

    Abstract: The invention relates to a method for the production of polyolefins at pressures of from 1 to 4,000 bar and temperatures of from 20 to 350 DEG C in the presence of a catalyst system, comprising an organometallic compound from the group of the metallocenes or the catalytically active iron, cobalt, nickel, or palladium complexes. The organometallic compound comprises a Lewis base functionality which is arranged such that said functionality can co-ordinate intramolecularly to the central metal atom of the organometallic compound. The reaction temperature is adjusted such that the resulting polyolefin has a bimodal molecular weight distribution MW/MN of

    Abstract: The invention relates to transition metal complexes of general formulas (Ia) or (Ib) in which the substituents and indices have the following meanings: M represents titanium, zirconium, hafnium, vanadium, niobium or tantalum or an element of the third subgroup of the periodic table or of the lanthanides; X represents fluorine, chlorine, bromine, iodine, hydrogen, C1-C10-alkyl, C6-C15-alkyl aryl having 1 to 10 C-atoms in the alkyl residue and 6 to 20 C-atoms in the aryl residue, -OR or -NR R ; n represents 1, 2, or 3, whereby n corresponds to the valence of M minus the number 2; Y represents (a), (b), (c) or (d); Z represents a triple-linking binding group and; A and A represent double-linking binding links. The invention also relates to a method for producing the transition metal complexes, to their production as compounds used as intermediate products, and to the use of transition metal complexes for the polymerization of olefins. Further, the invention relates to a method for the polymerization of olefins, homopolymerizates or copolymerizates of ethylene or of propylene having other C2-C12-alk-1-enes, to their use for producing films, fibers or shaped bodies, and to the films, fibers and shaped bodies made of these polymerizates.
