    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.
