SOLID CATALYTIC COMPONENT FOR POLYMERIZATION OF OLEFINS, CATALYST CONTAINING IT, AND USE THEREOF Russian patent published in 2007 - IPC C08F4/654 C08F10/00 C08F4/649 

FIELD: polymerization catalysts.

SUBSTANCE: catalytic component according to invention contains magnesium, titanium, halogen, and electron donor, wherein the latter contains at least one compound, notably polyol ester I having general formula R₁CO-O-CR₃R₄-A-CR₅R₆-O-CO-R₂ (I), wherein groups R₁ and R₂, the same or different, represent substituted or unsubstituted hydrocarbon residue having 1 to 20 carbon atoms; groups R₃-R₅, the same or different, are selected from group consisting of hydrogen, halogen, and above-defined hydrocarbon residue, said groups R₃-R₆ optionally containing one or several heteroatoms substituting carbon and/or hydrogen atom, wherein said heteroatoms are selected from group consisting of oxygen and halogen atoms, or two or more groups R₃-R₆ being connected with each other to form saturated or unsaturated monocyclic ring; and A represents bivalent linking group between two hydrocarbon radicals having from 1 to 10 atoms, said linking group being selected from group consisting of aliphatic, alicyclic, and aromatic bivalent radicals and can bear linear or branched C₁-C₂₀-substituents, provided that two or more substituents of said linking group and above-defined R₃-R₆ groups can be interconnected to form saturated or unsaturated monocyclic ring. Invention further discloses catalyst containing above-defined solid catalytic component and its employment in polymerization of CH₂=CHR hydrocarbons, wherein R represents hydrogen or C₁-C₆-alkyl group.

EFFECT: enabled preparation of polymers characterized by high stereoregularity and increased polymerization yield.
