Abstract: The invention relates to a process for the preparation of low- pressure ethylene polymers by polymerizing the monomers in the presence of a vanadium-containing Ziegler catalyst system, in which process the solid ethylene polymer obtained is reacted in the degassing zone with additives containing OH groups. The additives are preferably water or C1-C10-alcohols.
