METHOD OF PRODUCING COPOLYMERS OF ETHYLENE WITH BUTYL ACRYLATE Russian patent published in 2019 - IPC C08F2/02 C08F220/18 C08F210/02 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry, particularly to methods of producing copolymers of ethylene with acrylates by radical copolymerisation in bulk at high pressure. Reaction mixture of ethylene and butylacrylate is fed together with organic peroxide or a mixture of peroxides in the upper and lower parts of the reactor, wherein the value of the product of the rate constant of the decomposition of the individual peroxide or additive rate constant of the peroxide mixtures decomposition during the period of their stay in the upper part of the reactor in range of 81–95 is provided, and in the lower part of the reactor – within range of 41–48.

EFFECT: optimization of flow rate of initiators ensuring required quality of copolymer.
