FIELD: chemistry.
SUBSTANCE: invention relates to a catalyst composition for use as a precursor of a Ziegler-Natta catalyst system. Composition contains a combination of a magnesium fragment, titanium fragment and internal donor, containing at least one 1,2-phenylenedioate compound. 1,2-phenylenedioate is selected from a group, consisting of 1,2-phenylene diisopropanoate, 1,2-phenylene diisobutanoate, 1,2-phenylenedi-tert-butanoate, 2-acetoxyphenyl pivalate and 2-(pivaloyloxy)phenylbenzoate. Invention also discloses a Ziegler-Natta catalyst system, a method of producing a catalyst composition and a method for polymerisation and/or copolymerisation of olefins.
EFFECT: catalyst composition provides improved polymerisation characteristics for obtaining olefin-based polymers.
