Abstract:
1. A process for producing a solid catalyst component for olefin polymerization, comprising: reacting (a1) an oxide of at least one element that is selected from Group II to Group IV elements and that supports an alcohol-free halogen-containing magnesium compound with (b1) an alcohol at a hydroxyl group/magnesium molar ratio of 1.0 or more, and then with (c1) a halogen-containing silicon compound at a halogen/magnesium molar ratio of at least 0.20, reacting a reaction product from the compounds (a1), (b1) and (c1) with (d) an electron-containing compound and (e) a halogen-containing titanium compound at a temperature of at least 120° C. but no more than 150° C., and washing the resultant reaction mixture with an inert solvent to obtain a solid catalyst component.
