Abstract
Process for the polymerization of ethylene, characterized in that said polymerization is carried out at pressures of below about 100 atmospheres and at temperatures up to about 100ยบ with application of exciters for polymerization consisting of combinations of aluminum alkyl and metal combinations of the 4th.- 6th. secondary group of the periodic system, in the presence of auxiliary liquids consisting of hydrocarbon fractions that are to be applied repeatedly, a part of the auxiliary liquid being separated and released by distillation after a separation of catalyst residues, from all the parts that boil higher than the basic auxiliary liquids, the amount of the auxiliary liquid being measured, to be deduced, such that the polymerization is always carried out in the presence of such auxiliary liquids containing less than 1% by weight, preferably less than 0.5% by weight of the parts of higher degrees of boiling that are to be eliminated.
