Abstract

An ethylene polymerization process in which ethylene is polymerized in the presence of a chromium oxide and silica catalyst, under polymerization temperatures and pressures, characterized by determining the rate of swelling of the polyethylene product, and by adjusting, sensitive to it, the activation temperature of the catalyst and/or adjust, sensitive to this, the speed of the hydrogen passed to the polymerization zone, in order to obtain a polyethylene product with a desired swelling ratio.
