    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

    Abstract: A catalyst system (I) for the polymerisation of olefinic hydrocarbons contains (A) a metal-amidinato complex of formula (A) and opt. (B) an acceptor cpd. for substit. X in (A) as activator; M = Sub-Gp. III, IV, V or VI metal or lanthanide metal; X = negative leaving atom or gp. (these can be identical or different if (n = m) is greater than 1); R -R = C-organic or Si-organic gps.; n = valency of M in complex (A); m = 1-5; n - m = O or more. Also claimed is a process for the prodn. of homo- or copolymers of ethylene and other olefins by insertion polymerisation using catalyst (I). Also claimed are polymers of ethylene and alkyl- and aryl-substd. olefins obtd. by this process.

    Abstract: Process for the preparation of a supported catalyst for the polymerisation of alpha -olefins, in which (1) a support gel containing silicon dioxide is prepared by (1.1) introducing a sodium or potassium waterglass solution into a rotating stream of an aqueous mineral acid both longitudinally and tangentially to the stream, spraying the silicic acid hydrosol thus formed in droplet form into a gaseous medium, allowing it to solidify into a hydrogel and freeing the hydrogel thus obtained of salt by washing without prior aging, (1.2) drying the hydrogel resulting from (1.1) to form the support gel, and (2) the support gel (1) is loaded with chromium trioxide or a chromium compound which can be converted into chromium trioxide under the conditions of the process step (3), which results in a chromium-containing support gel, and (3) the chromium-containing support gel (2) is heated in an anhydrous gas stream containing oxygen in a concentration of over 10% by volume for from 10 to 1000 minutes at from 400 to 1100 DEG C, the hydrogel resulting from the process step (1.1) being dried in the process step (1.2) over a time of not more than 60 seconds in a shaping flash dryer at an inlet temperature of from 80 to 400 DEG C .
