POLYOLEFIN CATALYST COMPONENT CONTAINING MESOPOROUS MATERIAL, ITS PRODUCTION METHOD, AND ITS USE Russian patent published in 2022 - IPC C08F4/02 C08F10/00 C08F4/654 C08F4/656 

FIELD: chemistry.

SUBSTANCE: invention relates to thermally activated mesoporous material for the production of components of an olefin polymerization catalyst, a method for the production of a catalyst component, a catalyst component, and a method for polymerization of olefin in the presence of the specified catalyst component. Mesoporous material is mesoporous material based on silicon, wherein treatment for thermal activation of mesoporous material is carried out in inert atmosphere at a temperature from 300 to 900°C for a period of time from 3 to 48 h, while thermally activated mesoporous material is further subjected to treatment with chlor-containing silane and treatment in a ball mill, carried out separately or simultaneously. Mesoporous material, before treatment with thermal activation, is selected from a group consisting of: a) mesoporous material with a two-dimensional hexagonal structure of channels, having an average pore size from 4 to 15 nm, a specific surface area from 550 to 650 m²/g, and a pore volume from 0.5 to 1.5 ml/g; b) mesoporous material of an “eggshell” type with a two-dimensional hexagonal structure of channels, having a pore volume from 0.5 to 1.5 ml/g, a specific surface area from 100 to 500 m²/g, and an average pore size from 5 to 15 nm; c) spherical mesoporous silica with a volume-centered cubic structure, having a specific surface area from 700 to 900 m²/g, a pore volume from 0.5 to 1 ml/g, and an average pore size from 1 to 5 nm; and d) hexagonal mesoporous material with a structure of channels, similar to cubic cavities, a crystal structure of which has a volume-centered cubic structure Im3m, wherein this hexagonal mesoporous material has an average pore size from 4 to 15 nm, a specific surface area from 450 to 550 m²/g, and a pore volume from 0.5 to 1.5 ml/g.

EFFECT: provision of increased catalytic activity.
