Abstract
Process for the manufacture of pliolefins, especially polyethylene, by polymerization of ethylene at pressures of less than 100 atmospheres and temperatures up to approximately 100º with the application of catalysts consisting of mixtures of metal-organic combinations, especially aluminum-alkylated combinations, with metal combinations of the group secondary 4th of the periodic system, especially with titanic combinations, in the presence of an auxiliary liquid composed of hydrocarbon fractions in the boiling zone of benzine or diesel oil, characterized in that catalysts are used that, when applied in the polymerization reactor they still contain free titanic tetrachloride, in such amount and composition, that no more than 200 grams of dialkyl aluminum monochloride are found in 1 m of reaction mixture.
