FIELD: technological processes.
SUBSTANCE: invention relates to a method of producing polyethylene or an ethylene copolymer by high pressure polymerisation in the presence of two special peroxide polymerisation initiators in a wide temperature range. Described is a method of producing polyethylene or an ethylene copolymer, involving a step for radical polymerisation or copolymerisation of ethylene in the presence of a first peroxide polymerisation initiator, selected from diperketal peroxide compounds, and a second initiator other than said first initiator, also being a diperketal peroxide.
EFFECT: technical result is higher efficiency of polyethylene or copolymer of ethylene.
