PROCATALYST COMPOSITION WITH SUBSTITUTED AMIDE-ESTER AS INTERNAL ELECTRON DONOR Russian patent published in 2016 - IPC C08F4/654 C08F10/00 C08F10/06 C07C233/69 B01J31/02 B01J27/24

Abstract RU 2586973 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a procatalyst composition for polymerisation of olefin monomer. Composition contains a combination of magnesium fragment, a titanium fragment and internal electron donor. Internal electron donor is a substituted complex amide ester of structure (II). Invention also describes a catalyst composition and a method of producing an olefin-based polymer.

EFFECT: technical result is improved catalytic activity and/or improved catalyst selectivity of catalyst, as well as obtaining propylene-based polymer with high stereoregularity and a wide molecular weight distribution.
