Abstract
Process for the polymerization of ethylene at temperatures below about 100ยบ and pressures below about 100 atmospheres with the application of catalysts, which consist of a mixture of metal-organic combinations, especially aluminum-alkylated combinations, with metal combinations of the secondary groups of 4 -6 of the periodic system, especially with titanium compounds, for example titanium tetrachloride, characterized by introducing into the reactor for the polymerization during the polymerization such an amount of oxygen or oxygen-containing gases, for example air, which react to one kilogram of oxygen. Catalyst for the polymerization 2-200 liters of oxygen. (Machine-translation by Google Translate, not legally binding)
