PRODUCTION METHOD FOR CATALYST COMPONENT FOR OLEFIN POLYMERIZATION, PRODUCTION METHOD FOR CATALYST FOR OLEFIN POLYMERIZATION, AND PRODUCTION METHOD FOR OLEFIN POLYMER

The present invention pertains to a production method that is for a catalyst component for olefin polymerization and that comprises a step (3) for granulating, by spraying and drying, a water slurry of an ion exchangeable second layered silicate (B) having an average particle size of 0.03-0.4 [mu]m and a Rosin-Rammler distribution constant n of 1.5 or more as calculated from a particle size distribution thereof, to obtain ion exchangeable first layered silicate granulated particles (C), and a step (4) for bringing the obtained first layered silicate granulated particles (C) into contact with an acid to obtain chemically-treated, ion exchangeable, second layered silicate granulated particles (D). 本发明涉及一种烯烃聚合用催化剂组分的制造方法，该方法包括工序(3)：通过喷雾干燥将平均粒径为0.03μm至0.4μm和由其粒度分布计算的罗辛-拉姆勒分布常数n为1.5以上的离子交换性第二层状硅酸盐(B)的水性浆料造粒，得到离子交换性第一层状硅酸盐造粒颗粒(C)，和工序(4)：使得到的第一层状硅酸盐造粒颗粒(C)与酸类接触，得到化学处理的离子交换性第二层状硅酸盐造粒颗粒(D)。
