FIELD: chemistry. ^ SUBSTANCE: claimed invention relates to catalyst of olefin monomers trimerisation. Described is catalytic composition for olefin monomers trimerisation, which contains a) source of chrome, molybdenum or tungsten; b) ligand if general formula (I), in which X stands for bivalent organic group, selected from substituted or non-substituted alkylene groups, in case of substituted groups, substituents represent hydrocarbon groups; R1 and R3 represent cycloaromatic groups, which do not contain polar substituents in none of orto-positions; R2 and R4 are independently selected from obligatory substituted cycloaromatic groups, each of R2 and R4 having polar substituent in at least one orto-position; and c) cocatalyst. Also described is method of olefin monomers trimerisation, including interaction of at least one olefin monomer in conditions of trimerisation reaction with said above catalytic composition. ^ EFFECT: selective obtaining 1-hexagen from ethylene, reducing level of formation of by-products, especially C10. ^ 10 cl, 2 tbl, 12 ex |
