摘要：
A solid catalyst component for olefin polymerization superior in shatter resistance and narrowness of particle size distribution, is provided,
which component is prepared by
spraying a mixture of Mg compound with an alcohol in a molten state, in a column; cooling the inside of the column; to obtain a component (B); partly removing the alcohol from (B), to obtain a solid component (C); contacting a halogen-containing Ti compound and an electron donor with (C); to obtain (D); contacting (D) with a halogen-containing Ti compound;
in the above process,
specifying the composition formulas of (A), (B) and (C); specifying the X-ray diffraction spector of (C) in comparison of that of (B); and contacting (C) with a halogen-containing Ti compound and an electron donor using an aliphatic hydrocarbon of a specified b.p., in a specified temperature.
