Abstract

A process comprising the polymerization of ethylene and its conversion into a normally solid polymer, in a hydrocarbon medium, in the presence of a catalyst characterized by chromium oxide and at least one oxide which is silica, alumina, zirconium oxide or thorium oxide , and of a compound represented by the formula ZnR2, in which R is hydrogen or an alkyl, cycloalkyl or aryl radical, or combinations of these radicals, said radical having from one to 20 carbon atoms, at least one of which is R a hydrocarbon radical, and the proportion of said compound being from 0.1% to 15% by weight, based on the weight of said oxide catalyst, and regulated in order to increase the productivity of the catalyst.
