RADICAL POLYMERISATION OF ETHYLENE, INITIATED BY A PAIR OF HIGH-PERFORMANCE ORGANIC PEROXIDES Russian patent published in 2021 - IPC C08F10/02 C08F110/02 C08F2/38 C08F4/38 

Abstract RU 2742275 C1

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.
