Process for the preparation of polymers of ethylene, optionally of copolymers with other monomers, in the presence of chain regulators and optionally inhibitors and other co-reactants by initiation of free radical-forming compounds in multi-zone reactors at 50 to 400C and above 500 at. A stable reaction and a high The degree of conversion is achieved by the use of a peroxide system in the 1st zone and of peroxide-oxygen systems in the following reaction zones, the reaction mixture temperatures in the individual zones being set to increasing values. |
