MAGNESIUM HALIDE SOLUTION AND METHOD FOR PRODUCTION THEREOF AND USE THEREOF Russian patent published in 2019 - IPC C08F4/649 C08F10/00 C08F10/02 C08F110/00 C08F110/02

Abstract RU 2688937 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a magnesium halide solution for preparing a catalyst for olefin polymerisation. Magnesium halide solution contains magnesium halide, organic oxygen-containing titanium compound, hydroxy group-containing compound, organic solvent and additionally organic heterocyclic compound. Organic solvent is hydrocarbon and/or halogenated hydrocarbon. Organic heterocyclic compound is at least one selected from a group comprising an organic sulphur-containing heterocyclic compound, organic nitrogen-containing heterocyclic compound and organic epoxy compound. Also disclosed are a method of producing a magnesium halide solution and use thereof for producing an olefin polymerisation catalyst.

EFFECT: disclosed solution has good stability and can be used to obtain a highly efficient catalyst for olefin polymerisation.
