Title:

METHOD FOR PREPARATION OF A CATALYST COMPONENT USED FOR OLEFIN POLYMERIZATION

Document Type and Number:

WIPO Patent Application WO/2015/165405

Kind Code:

A1

Abstract:

The present invention provides a method for preparation of a catalyst component used for olefin polymerization; first dissolving an anhydrous magnesium halide in a mixed solvent containing an oxygen-containing organotitanium compound, an organic epoxy compound, a hydroxyl-containing compound, and an inert diluent to form a magnesium halide solution, the mixed solvent containing no phosphate ester compounds; said magnesium halide solution is then mixed with a halogen-containing compound, and solid is precipitated to obtain the catalyst component; said halogen-containing compound comprises at least one of a halogen- and titanium-containing compound, a halogenated organic hydrocarbon compound, an acyl halide compound, a halogen- and phosphorous-containing compound, a boron-containing compound, a halogenated organoaluminum compound, and a halogen- and silicon-containing compound. The catalyst component prepared according to the present invention has a good particle morphology and excellent hydrogen transfer properties, facilitating the use of the catalyst in a slurry or gas phase polymerization device.
