  • METHOD FOR PRODUCING SOLID CATALYST COMPONENT FOR OLEFIN POLYMERIZATION, METHOD FOR PRODUCING CATALYST FOR OLEFIN POLYMERIZATION, AND METHOD FOR PRODUCING OLEFIN POLYMER
    Publication number: 20230093632
    Abstract: Disclosed herein is a method for producing a solid catalyst component for olefin polymerization that is capable of reducing the amount of fine powder contained in the solid catalyst component for olefin polymerization. The method includes the step of reacting a magnesium compound and a titanium halide compound with each other so that a maximum heat release rate per mole of the magnesium compound is 18 W or less. Also disclosed herein is a method for producing a solid catalyst component for olefin polymerization that is capable of preventing a reduction in polymerization activity caused by application of heat to the solid catalyst component for olefin polymerization. The method includes the step of reacting a magnesium compound and a titanium halide compound with each other so that a total heat release value per mole of the titanium compound is 6 kJ to 90 kJ.
