Abstract

A solid catalyst component for olefin polymerization, which is obtained by reacting the following compounds (a), (b) and (d), or the following compounds (a), (b), (c) and (d), (a) a halogen-containing titanium compound, (b) an alkoxylated magnesium compound, (c) a halogen-containing silicon compound, (d) electron-donating compound(s) represented by the following general formula (I) and/or general formula (II), 1 wherein n is an integer of 2 to 10, each of R.sup.1 to R.sup.8 is a substituent having at least one element selected from carbon, hydrogen, oxygen, halogen, nitrogen, sulfur, phosphorus, boron or silicon, any substituents of R.sup.1 to R.sup.8 may together form a ring other than a benzene ring, 2 wherein each of R.sup.9 to R.sup.12 is independently a linear, branched or cyclic alkyl group, or an arylalkyl group, having 1 to 20 carbon atoms, provided that the total sum of carbon atoms of R.sup.9 and R.sup.10 is 3 to 40.
