Abstract
The present invention relates to a method for producing a catalyst component for olefin polymerization, the method including step (3): granulating, by a spray drying, an aqueous slurry of an ion-exchangeable second layered silicate (B) that satisfies that an average particle diameter is 0.03 μm to 0.4 μm, and a Rosin-Rammler distribution constant n determined from a particle size distribution is 1.5 or more; and step (4): bringing the obtained first layered silicate granulated particles (C) into contact with acid to obtain chemically treated ion-exchangeable second layered silicate granulated particles (D).
