FIELD: petrochemical processes.
SUBSTANCE: hydrocarbon feedstock containing one or more C3-C20-olefins is polymerized in presence of catalyst composed of a transition metal and a bulky ligand, after which at least one preliminarily isolated fraction of the product, whose properties are beyond a certain range of preliminarily chosen desired properties, is subjected to oligomerization.
EFFECT: improved properties of desired product.
