    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 .

    Abstract: A novel Phillips catalyst for the homopolymerisation of ethylene and the copolymerisation of ethylene with alpha -olefins contains, as catalytically active components, a specific aluminium phosphate-supported chromium catalyst and cocatalysts of the general formulae I to IV MR M R2 M R 3-nXn MM RR@ (I) (II) (III) (IV> in which the index and variables have the following meanings: M is lithium, sodium or potassium, M is magnesium or zinc, M is boron or aluminium, R is C1- to C10-alkyl or C6- to C20-aryl, R is R or C1- to C10-alkoxy or C6- to C20-aryloxy, X is chlorine, bromine or iodine, N is 0, 1 or 2. The aluminium phosphate-supported chromium catalyst is obtainable by applying chromium compounds to a finely divided aluminium phosphate having a P:Al molar ratio of close or equal to 1 and a pore volume of > 1 cm /g, and activating the resulting intermediate at elevated temperatures in an oxidising atmosphere. The novel Phillips catalyst has an extremely long mean service life, and its productivity can be further increased by adding hydrogen.

    Abstract: Polymers of ethylene are obtainable by polymerization of ethylene and, if desired, further comonomers in the presence of a catalyst system comprising as active constituentsI) a Phillips catalyst,II) a solid which is different from I) and comprises a component which is derived from the metallocene complexes of the formula (A) in which the substituents and indices have the following meanings: R1 to R10 are hydrogen, C1-C10-alkyl, 5-to 7-membered cycloalkyl which may in turn bear C1-C6-alkyl groups as substituents, C6-C15-aryl or aryalkyl, where two adjacent radicals may also together form a cyclic group having from 4 to 15 carbon atoms, or Si(R11)3, where R11 is C1-C10-alkyl, C6-C15-aryl or C3-C10-cycloalkyl, or the radicals R4 and R9 together form a group -[Y(R12R13)]m-, where Y is silicon, germanium, tin or carbon, and R12, R13 are hydrogen C1-C10-alky, C3-C10-cycloalyl or C6-C15-aryl,M is a metal of transition groups IV to VIII or a metal of the lanthanide series,Z1, Z2 are fluorine, chlorine, bromine, iodine, hydrogen, C1-C20-alkyl or aryl, -OR14, -OOCR14, where R14 is hydrogen or C1-C20-alkyl; R15 is C1-C20-alkyl; m is 1,2,3 or 4; n is 0, or 2; r is 0, 1 or 2; the sum n+r is likewise 0, 1 or 2, and, if desired,III) an organometallic component selected from groups IA, IIA, IIB and IIIA of the Periodic Table of the Elements.
