FIELD: chemistry.
SUBSTANCE: invention relates to a multifunctional polymer which contains a graft polymer formed from: a) polyolefin, b) nitrogen-containing ethylene-unsaturated aromatic or aliphatic monomer which contains from 2 to approximately 50 carbon atoms; and c) an organometallic compound capable of reacting with the said polyolefin. The invention also discloses multifunctional polymers (versions), a synthesis method thereof, and lubricating oil (versions).
EFFECT: invention enables to obtain a multifunctional polymer which acts as a dispersing agent, viscosity index improver and an antiwear additive.
