Abstract

1. A process for the treatment of a spherical catalyst for the polymerization of olefins, containing at least one transition metal, a magnesium compound and a halogen, characterized in that ethylene is prepolymerized in the presence of a cocatalyst selected from the alkyl aluminiums and at least partially in suspension, to a degree of prepolymerization suitable for the process of polymerization in suspension or in the gaseous phase in which the prepolymer will subsequently be used, a sphere protector which is the product of the reaction between alkyl aluminium and an electron donor being associated with the various components at the latest after prepolymerization.
