Method for producing solid catalyst component for olefin polymerization, catalyst for olefin polymerization and a process for propylene polymerization

A method for producing an olefin polymerization catalyst component, the method comprising:

• bringing a magnesium compound, a tetravalent titanium halide compound, an organic compound represented the following general formula (1)
• R1k(C6H4-k)(COOR2)(COOR3) (1) and
• an organic compound represented the following general formula (2)
• R4R5C═C(COOR6)(COOR7) (2)
• into contact with each other at the same step,
• wherein R1 is a halogen atom or an alkyl group having 1 to 8 carbon atoms, R2 and R3 are a linear alkyl group having 1 to 6 carbon atoms, provided that R2 and R3 are either identical or different, and k is an integer from 0 to 4, provided that a plurality of R1 are either identical or different when k is an integer from 2 to 4, and
• wherein R4 and R5 are independently an atom or group selected from a hydrogen atom, halogen, a linear alkyl group having 1 to 20 carbon atoms, a branched alkyl group having 3 to 20 carbon atoms, a vinyl group, a linear or branched alkenyl group having 3 to 20 atoms, a cycloalkenyl group having 3 to 20 carbon atoms, an aromatic hydrocarbon group having 6 to 20 carbon atoms, provided that R4 and R5 optionally bond to each other to form a ring, and the number of carbon atoms of R5 is 2 or more when R4 is a hydrogen atom or a methyl group;
• and
• wherein R6 and R7 are independently a linear alkyl group having 1 to 20 carbon atoms, a branched alkyl group having 3 to 20 carbon atoms, a vinyl group, a linear or branched alkenyl group having 3 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, a cycloalkenyl group having 3 to 20 carbon atoms, or an aromatic hydrocarbon group having 6 to 20 atoms.
