The present invention relates to a process for producing a, solid catalyst component for olefin polymerization, a process for producing . a solid catalyst for olefin polymerization and a process for producing an olefin polymer.

Background Art

[0002]

Conventionally, as a catalyst component for olefin polymerization, many solid catalyst components containing a titanium atom, a magnesium atom, a halogen atom, and an internal electron donor have been proposed. Catalysts using these solid catalyst components are desired to have a high polymerization activity in polymerization of an olefin and, at the same time, to give a polymer having a small content of a component which is dissolved out into a low temperature organic solvent such as a low-molecular weight component and an amorphous component .

[0003]

It is known that performance of a catalyst component for olefin polymerization is improved by bringing a catalyst component precursor for olefin polymerization into contact with a plurality of organic compounds, and it has been made known that contacting a carboxylic halide compound is effective. See, for example, JP-B-60-359 (Patent Document 1) and JP-B-63-34169 (Patent Document 2) .

[0004]

In addition, a catalyst in which an aliphatic dicarboxylic acid diester is used as an internal electron donor has been proposed, and JP-A-2-252704 (Patent Document 3) describes polymerization of propylene in the presence of a catalyst formed of a titanium trichloride composition, an organoaluminum compound, an organosilicon compound, and a fatty acid ester compound such as adipate as an internal electron donor.

(1) Synthesis of solid catalyst component

After a 500 ml flask equipped with a stirrer, an addition funnel and a thermometer was replaced with nitrogen, a toluene slurry containing 40 g of the solid catalyst component precursor obtained in Example 1(1) was charged thereinto, and toluene was charged thereinto so that the total volume of the slurry might be 232 ml. Then, 36 ml of tetrachlorosilane and 42 ml of bis (2-ethylhexyl) dodecanedioate were charged thereinto, and the mixture was heated to stir at 105°C for 2 hours. Then, solid-liquid separation was performed, and washing of the resulting solid with 230 ml of toluene at 105 °C was repeated three times, thereafter 128 ml of toluene was added and 23 ml of dichloride dodecanedioate was charged, and the mixture was stirred at 105 °C for 2 hours. Then, solid-liquid separation was performed, and washing of the resulting solid with 230 ml of toluene at 105 °C was repeated three times, thereafter 128 ml of toluene was added and 20 ml of titanium tetrachloride was charged, and the mixture was stirred at 105 °C for 2 hours. Then, solid-liquid separation was performed, and washing of the resulting solid with 230 ml of toluene at 105°C was repeated six times, thereafter, washing with 230 ml of hexane was further repeated three times at room temperature, and the solid after washing was dried to obtain a solid catalyst component. The resulting solid catalyst component for olefin polymerization contained 2.28 wt% of a titanium atom and 19.7 wt% of bis (2-ethylhexyl) dodecanedioate .

(2) Polymerization of ethylene and 1-butene

According to the same manner as that of Example 1 (3) except that the solid catalyst component was changed to 18.6 mg of the solid catalyst component obtained in (1) , polymerization was performed to obtain 50 g of a polymer. The obtained polymer had SCB of 14.5 and CXS of 5.3% by weight.
