    Abstract: Ziegler-Natta type catalyst system (ZNC), containing (a) a titanium-based solid component containing compounds of Ti and magnesium, a halogen, an inorganic oxide support (IOS) and a carboxylate ester as electron donor, (b) an aluminium compound and (c) optionally another electron donor, in which the oxide (IOS) has a pH of 1-6, an average particle diameter of 5-200 microns and an average primary particle diameter of 1-20 mu m, and contains pores or channels with an average diameter of 0.1-20 mu m in amounts of 5-30 vol%. Also claimed is (i) a process for the production of ZNC by interacting components (a), (b) and (c) together at 0-150 degrees C and 1-100 bar; (ii) a process for the production of polymers of 2-20C alk-1-enes by polymerisation of the alkene (preferably propylene) and optionally other comonomers at 20-150 degrees C and 1-100 bar in presence of (ZNC); (iii) polymers of propylene obtained by this process.

    Abstract: The invention relates to metallocene complexes of the general formula (I), wherein: M is a metal from subgroups III, IV, V or VI of the periodic table of elements or a metal from the lanthanides; X is fluorine, chlorine, bromine, iodine, hydrogen, C1-C10 alkyl, C6-C15 aryl or -OR , wherein R is C1-C10 alkyl, C6-C15 aryl, alkyl aryl, aryl alkyl, alkyl fluoride or aryl fluoride with, respectively, 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; R to R and R to R are hydrogen, C1-C10 alkyl, 5- to 7-membered cycloalkyl, which in turn can carry C1-C10 alkyls as substituents, C6-C15 aryl or aryl alkyl, wherein two adjacent radicals may together stand for cyclic groups containing 4 to 15 C atoms, or Si(R )3 with R being C1-C10 alkyl, C6-C15 aryl or C3-C10 cycloalkyl; Y is nitrogen, phosphorous, arsenic, antimony or bismuth; R , R are hydrogen, C1-C10 alkyl, C3-C10 cycloalkyl or C6-C15 aryl; n is 0, 1 or 2; and Z stands for halogenides, carboxylates, monosubstituted sulfonates, borates or alcoholates. The invention also relates to ligand systems of the general formula (II) as intermediates.

    Abstract: Polyalk-1-enes are prepared by polymerization of alk-1-enes with the aid of the compound bis(cyclopentadienyl)-chromium(II)in which the cyclopentadienyl rings may carry inert organic radicals, said compound being adsorbed on an inorganic oxide carrier, by a process in which the polymerization is carried out in the presence of an organometallic compound of a metal of main groups I to III or of a metal hydride, in particular of n-butyl-lithium.
