CATALYST INGREDIENTS FOR HOMOPOLYMERIZATION OR COPOLYMERIZATION OF OLEFINS Russian patent published in 2018 - IPC C08F4/651 C08F4/654 C08F110/06 

FIELD: technological processes.

SUBSTANCE: invention relates to solid ingredient of catalyst, catalyst, and method of homopolymerization or copolymerization of olefins. Solid ingredient of catalyst forhomopolymerization or copolymerization of olefins comprises Mg, Ti and electron-donor compound of formula (I), wherein Z is selected from C, where groups R², identical or different from each other, are hydrogen or C₁-C₂₀ hydrocarbon radicals that can be joined together to form a single cycle; m is a number equal to valence of Z, and n is integer from 1 to 6, wherein group (ZR²_m)_n of the formula (I) is selected from the group consisting of aliphatic diradicals, aliphatic diradicals substituted with C₁-C₂₀ alkyl radicals, aromatic divalent radicals and aromatic divalent radicals substituted with C₁-C₂₀ alkyl radicals; R¹ are selected from C₁-C₁₅ alkyl groups, phenyl group, phenyl groups substituted with halogen and/or C₁-C₅ alkyl groups; R³ is hydrogen or C₁-C₁₅ hydrocarbon radicals; R⁴ are selected from hydrogen or C₁-C₁₀ alkyl groups. Formula (I): .

EFFECT: catalyst system based on a solid catalyst ingredient has high activity and stereospecificity.
