(57) [Summary] [Purpose] Polymer particles that exhibit high activity, high stereoregularity, can control the particle size in a wide range, and can be molded as they are for homopolymerization of olefins and copolymerization with other olefins. The resulting catalyst component is provided. (Structure) (A) Polymer particles of a carrier having an arbitrary particle size, (B) dihydrocarbyl magnesium and (C) Olefin polymerization capable of controlling particle size, which comprises contacting a solid obtained by contacting a compound containing a hydrocarbyloxy group with (D) a halogen-containing alcohol, and further contacting (E) an electron-donating compound and (F) a titanium compound. For producing catalyst components for automobiles. |
