    Abstract: Production of homopolymers or copolymers of ethylene by homopolymerization of ethylene or copolymerization of mixtures of ethylene and other monomers at superatmospheric pressure and elevated temperature under the influence of a free radical generating polymerization initiator with or without a polymerization regulator. The initiator used is a mixture of (a) an initiator having a halflife of ten to 30 hours at 50 DEG C and (b) an initiator having a halflife of 0.2 to 10 hours at 50 DEG C, the halflife at 50 DEG C of initiator (a) being at least twice as long as that of initiator (b). Polymers having a high molecular weight and a low degree of branching are obtained in a fairly high yield.
