FIELD: chemistry.
SUBSTANCE: described is a method of producing an olefin oligomer obtained via trimerisation of an olefin monomer with 2-6 carbon atoms using a trimerisation catalyst system. The catalyst system is prepared by mixing a chromium source, a nitrogen-containing ligand and alkyl aluminium. The alkyl aluminium is exposed to microwaves with frequency 0.3-20 GHz for 0.5-20 minutes.
EFFECT: high efficiency of trimerisation reaction at low pressure of olefin monomer.
