    摘要: A production process is provided for an olefin polymerization catalyst component precursor, including the steps of (I) adding an organomagnesium compound to a solution containing a solvent, a Si—O bond-containing silicon compound, and a defined titanium compound, under agitation, and continuing the agitation until a magnesium concentration in a liquid phase of a reaction mixture decreases to 9 ppm by weight or lower, and (II) solid-liquid separating the reaction mixture. A production process is also provided for an olefin polymerization catalyst component using the above precursor. Further, producing process is provided for an olefin polymerization catalyst using the above catalyst component. Still further, a production process is provided for an olefin polymer using the above catalyst.

    摘要: The present invention aims at providing a process for producing a solid catalyst for olefin polymerization, the solid catalyst component being capable of providing a polymer having high stereoregularity when an α-olefin is polymerized; a process for producing a solid catalyst component, which is used for producing the solid catalyst; and a process for producing an olefin polymer using the solid catalyst. This object can be achieved by a process for producing a solid catalyst component (A), the process including a step of bringing a titanium compound (a), a magnesium compound (b) and an internal electron donor represented by Formula (I) into contact with each other: where R1 is a hydrocarbyl group having 1 to 20 carbon atoms; R2, R3, R4, and R5 are each independently selected from a hydrogen atom, a halogen atom and a hydrocarbyl group having 1 to 20 carbon atoms, and at least one selected from R2, R3, R4, and R5 is a hydrocarbyl group having 1 to 20 carbon atoms; and R6 is a halogen atom.
