Abstract
A method for the polymerization or copolymerization of ethylene comprising polymerizing the ethylene at a pressure greater than 500 bars, at a temperature in the range 160.degree. to 280.degree.C and under conditions in which polymerization takes place in a single liquid phase, in the presence of a catalyst system comprising A. an alkylsiloxalane derivative of the formula, ##EQU1## and B. a halogenated titanium compound of the titanium trichloride type, the Al/Ti ratio between the constituents being between 1 and 10.
