FIELD: chemistry.
SUBSTANCE: invention relates to a method of polymerising olefins and a catalyst composition for producing olefins. Described is a catalyst composition containing an activator substrate, an organoaluminium cocatalyst and a semi-metallocene titanium compound with a phosphinimide ligand.
EFFECT: catalytic composition is used to obtain polymers of olefins having relatively wide molecular weight distribution and low content of long side chains.
