Abstract of Disclosure In a process for the preparation of a supported catalyst for the preparation of polyolefins which have a component A and a component B, wherein component A consists essentially of a reaction product of a compound of a first metal of sub groups IV to VI of the Periodic Table of the Elements with an organic compound of a second metal of main groups I to III of the Periodic Table of the Elements, said reaction being carried out at a temperature of from - 60°C to + 40°C, and an inorganic carrier, component B being an organo metallic compound, the improvement comprising suspending the carrier in an agent which is oxygen, sulfur, and moisture free, simultaneously and separately adding to the carrier and the agent the compounds of the first and second metals in liquid or dissolved form, excluding oxygen and moisture from the reaction, and maintaining a molar ratio of the compound of the first metal to the compound of the second metal of 1:3 to 3:1. ABSTRACT The use of the catalyst in the polymerization of ethylene both wich and without the presence of ? olefins is also disclosed.
