    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.

    Abstract: A process for the preparation of homopolymers of ethylene or copolymers of ethylene with secondary amounts of other C3- to C12-alk-1-enes by catalytic polymerisation in a suspension or in the gas phase in the presence of an antistatic at a temperature of from 50 to 120 DEG C and at a pressure of from 5 to 50 bar, characterised in that the antistatic employed is a mixture of the following substances: a) a metal salt of medialanic acid of formula (I) , b) a metal salt of an anthranilic acid of formula (II) , where the organic radical R is either alpha ) -CO-(CH2)x-CH3 (III alpha ) or ss) -CO-(CH2)y-CH=CH-(CH2)z-CH3 (IIIss), where x, y and z are each an integer, and x is in the range from 6 to 18, y is in the range from 1 to 16, z is in the range from 1 to 16 and y + z is in the range from 4 to 17, and c) a polyamine obtainable by reacting epichlorohydrin with an aliphatic primary monoamine or an N-alkylalkylenediamine of the formula (IV> R NH-R -NH2 (IV), where R is a C8-C24-alkyl radical and R is a C2-C6-alkylene radical. d
