FIELD: chemistry.
SUBSTANCE: invention relates to additives, intended for application in methods of polymerisation. Described is method of olefin polymerisation with formation of olefin-based polymer in polymerisation reactor. Method includes introduction of additive of polyetheramine and catalytic system into polymerisation reactor. Polyetheramine additive represents polyetheramine, where polyetheramine includes main polymer chain, containing at least one aminogroup at the end, main polymer chain includes at least one monomer, selected from the group, which includes ethylene oxide, propylene oxide, 1,2-butylene oxide and tetramethylene oxide. Method for ethylene and α-olefin copolymerisation and catalytic system for polymerisation of olefins are also described.
EFFECT: regulation of static charge, restricting formation of coating in reactor, due to introduction of polyetheramine.
