ABSTRACT:
A solid catalyst component for olefin polymerization having a high polymerization activity and affording a highly stereoregular polymer having a good particulate form, and a process for producing the same are provided, which component indispensably contains Mg, Ti, Al, halogen and alkoxy group; has two absorption peaks (absorbances A.sub.1 and A.sub.2) at specified wavenumbers within a specified region of spectra according to infrared spectrophotometry, A.sub.1 /A.sub.2 and A.sub.1 /A.sub.3 (A.sub.3 : an absorbance at a specified wavenumber) being each in a specified range; and has X-ray diffraction spectra distinctive from those of Mg halide or its complex with electron donor, and which process consists of step I of dissolving (a) anhydrous Mg dihalide, (b) a specified orthotitanic or polytitanic acid ester and (c) a specified alcohol in an inert hydrocarbon solvent to prepare component A; step II of mixing and reacting component A with component B consisting of (d) a specified organic acid ester, (e) a specified Al halide and (f) a specified Si halide to prepare solid product (I); and step III of reacting solid product (I) with component C consisting of (g) a specified Ti halide and/or (h) a specified vanadyl or vanadium halide to obtain solid product (II) as the objective catalyst component.
