example 1
[0240](i) Into a flask with an internal volume of 500 mL that was equipped with a stirring device and replaced with nitrogen gas, 20 g (175 mmol) of diethoxymagnesium, 140 mL of toluene, 40 mL of titanium tetrachloride and 17.3 mmol (4.3 g) of dipropyl phthalate were added, thereby obtaining a first contact product.
[0241](ii) The temperature of the first contact product described above was elevated, and in the middle of the temperature elevation at 90° C., 16.8 mmol (3.6 g) of 2-isopropyl-2-isopentyl-1,3-dimethoxypropane was added. The temperature was further elevated to 113° C. and the reaction was allowed for 180 minutes at a state of retaining the same temperature. After the reaction was completed, a second contact product, which was the reaction product, was washed four times with 187 mL of toluene at 100° C.
[0242](iii) Next, to the washed second contact product described above, 200 mL of a new toluene solution containing 15 vol % of titanium tetrachloride was added, and the tem...

[0248]A solid catalyst component for polymerization of an olefin was prepared in the same manner as in Example 1 except that a mixed solution of 0.01 mmol of dicyclopentyldimethoxysilane (DCPDMS) and 0.12 mmol of propyltriethoxysilane (PTES) was used instead of 0.13 mmol of cyclohexylmethyldimethoxysilane (CMDMS), and from this solid catalyst component, a catalyst for polymerization of an olefin was formed and a polymerization reaction was carried out, thereby obtaining a propylene homopolymer.
[0249]For the solid catalyst component for polymerization of an olefin obtained at this time, the results of component analysis and physical property evaluation are shown in Table 1 and Table 2, respectively, and the results of polymerization evaluation and evaluation of the amount of oligomers of the obtained propylene homopolymer are also shown in Table 3.
example 3
[0250]A solid catalyst component for polymerization of an olefin was prepared in the same manner as in Example 1 except that 0.13 mmol of dicyclopentylbis(ethylamino)silane (DCPBEAS) was used instead of 0.13 mmol of cyclohexylmethyldimethoxysilane (CMDMS) and that 1.5 liters of hydrogen gas was used instead of 3.0 liters of hydrogen gas. From this solid catalyst component, a catalyst for polymerization of an olefin was formed and a polymerization reaction was carried out, thereby obtaining a propylene homopolymer.
[0251]For the solid catalyst component for polymerization of an olefin obtained at this time, the results of component analysis and physical property evaluation are shown in Table 1 and Table 2, respectively, and the results of polymerization evaluation and evaluation of the amount of oligomers of the obtained propylene homopolymer are also shown in Table 3.
