Abstract

The present invention relates to a process for the preparation of ethylene polymers using a number of reactors arranged in series comprising the steps in which Advantage of the process of the present invention is mainly to decrease catalyst consumption for the same polyethylene production, in other words to increase the productivity. In a most preferred embodiment the process of the present invention is carried out in two loop reactors under slurry conditions.
