METHOD OF PRODUCING ETHYLENE COPOLYMER Russian patent published in 2016 - IPC C08F210/16 C08F210/18 C08F210/06 C08F2/18 C08F4/68 

FIELD: chemistry.

SUBSTANCE: method includes polymerising the mixture of monomers containing ethylene, at least one C_3-12 α-olefin and optionally at least one unconjugated C_4-20 diene in a suspension in the presence of a catalyst system. The catalyst system contains the suspension of a catalyst selected from a number comprising vanadium compounds in oil, a cocatalyst selected in the absence of organic solvents from a number comprising aluminium compounds, an activator selected in the absence of an organic solvent from a number comprising chlorine compounds.

EFFECT: obtaining elastomeric polymers having low gel content.
