Problems solved by technology

Since the former requires a blending step, production costs become higher
In addition, the obtained blend is excellent in formability, but the mechanical strength which is an advantage of metallocene-based polyethylene decreases

[0220] 4. Preparation method of catalyst for olefin polymerization

[0221] There is no particular limitation on the method of contacting the components when obtaining a catalyst for olefin polymerization consisting of the component (A) of the metallocene compound which is an essential component of the production method of the olefin-based polymer of the present invention, and Component (A) is reacted to form component (B) of a cationic metallocene compound and component (C) as a fine particle carrier, and for example, the following method may be arbitrarily employed.

[0222] (I) After component (A) and component (B) are brought into contact with each other, component (C) is brought into contact therewith.

[0223] (II) After component (A) and component (C) are brought into contact with each other, component (B) is brought into contact therewith.

[0224] (III) After component (B) and component (C) are brought into contact with each other, component (A) is brought into conta...

[0452] (1) Preparation of solid catalyst

[0453] Under a nitrogen atmosphere, 5 g of silica calcined at 600° C. for 5 hours was put into a 200 ml two-necked flask, and dried under reduced pressure by means of a vacuum pump for 1 hour while heating on a 150° C. oil bath. 69 mg of metallocene compound A was put into a separately prepared 100 ml two-necked flask under a nitrogen atmosphere, and the compound was dissolved in 13.4 ml of dehydrated toluene. At room temperature, 8.6 ml of a 20% methylaluminoxane / toluene solution manufactured by Albemarle Corporation was added to the toluene solution of the metallocene compound A, followed by stirring for 30 minutes. While heating and stirring a 200-ml two-necked flask containing vacuum-dried silica placed therein on an oil bath at 40°C, the reaction product of the entire amount of metallocene compound A with methylaluminoxane Toluene solution was added to it. After the whole was stirred at 40° C. for 1 hour, the toluene solvent wa...

Embodiment 2

[0459] In addition to using 11 mg of the solid catalyst obtained in the preparation of the solid catalyst in (1) of Example 1, introducing 85 ml of hydrogen gas under normal pressure before introducing ethylene containing 10% by weight of 1-butene, and changing the polymerization time to Except for 34 minutes, an ethylene-1-butene copolymer was produced in the same manner as in Example 1.

[0460] As a result, 31.4 g of an ethylene-1-butene copolymer was formed. The MFR of the obtained copolymer was 0.62 g / 10 minutes. The polymerization conditions are summarized in Table 14 and the polymerization results are summarized in Table 15.

Abstract

A metallocene compound represented by general formula (1) (wherein each symbol is as defined in the description).

Description

technical field [0001] The present invention relates to a metallocene compound, a catalyst component for olefin polymerization and a catalyst for olefin polymerization comprising the same, and a method for producing an olefin polymer using the catalyst for olefin polymerization. More specifically, the present invention relates to a metallocene compound having a substituent on a cyclopentadienyl ring and having bridged cyclopentadiene-indene as a basic skeleton, a catalyst for olefin polymerization comprising the metallocene compound A component and a catalyst for olefin polymerization, and a method for producing an olefin polymer (in particular, an ethylene-based polymer) using the catalyst for olefin polymerization. Background technique [0002] As a method for improving the formability of metallocene-based polyethylene that is generally poor in formability, a method of blending high-pressure-processed low-density polyethylene into metallocene-based polyethylene and using a...
