Embodiment

[0261] Hereinafter, the present invention will be described more specifically based on examples, but the present invention is not limited to these examples.

Synthetic example 1

[0262] [Synthetic Example 1] ([methylphenylmethylene (η 5 - cyclopentadienyl) (η 5 Synthesis of -2,7-di-tert-butylfluorenyl)]zirconium dichloride)

[0263] (i) Synthesis of 6-methyl-6-phenylfulvene (6-methyl-6-phenylfulvene)

[0264] Under a nitrogen atmosphere, 7.3 g (101.6 mmol) of lithium cyclopentadiene and 100 mL of dehydrated tetrahydrofuran were added to a 200 mL three-necked flask and stirred. The obtained solution was cooled with an ice bath, and 15.0 g (111.8 mmol) of acetophenone was added dropwise thereto. Afterwards, stirring at room temperature for 20 hours, the resulting solution was quenched with dilute aqueous hydrochloric acid. 100 mL of hexane was added to extract the soluble components, and the obtained organic layer was washed with water and saturated brine, respectively, and dried over anhydrous magnesium sulfate. Then, the solvent was distilled off, and the obtained viscous liquid was separated by column chromatography (hexane), whereby the target pr...

manufacture example 1

[0269] [Production Example 1] (Synthesis of Liquid Ethylene-Propylene Copolymer Using Vanadium Catalyst)

[0270] Add 1 liter of dehydrated and purified hexane to a 2 liter continuous polymerization reactor with stirring blades that has been fully replaced with nitrogen, and feed it continuously at 500 mL / h for 1 hour to adjust to 96 mmol / L Sesquiethyl aluminum chloride (Al(C 2 h 5 ) 1.5 · Cl 1.5 ) hexane solution, and further, as a catalyst, continuously supply VO(OC 2 h 5 ) Cl 2 The hexane solution was continuously supplied with 500 mL / h of hexane. On the other hand, the polymerization liquid was continuously discharged from the upper part of the reactor so that the polymerization liquid in the reactor was constant at 1 liter.

[0271] Next, ethylene gas was supplied in an amount of 35 L / h, propylene gas was supplied in an amount of 35 L / h, and hydrogen gas was supplied in an amount of 80 L / h using a bubbling tube. The copolymerization reaction was performed at 35° C...

Abstract

This invention pertains to a resin composition, a molded body, a fiber, a film, and a sheet. The resin composition contains at least two types of polyolefin resin (A) and 0.05%-10% by mass of an alpha-olefin (co)polymer (B) that fulfills conditions (b-1)-(b-3). (b-1) The methyl group index is 40%-60%, the methyl index is ratio of integral value of peak in range of 0.50-1.15 ppm to integral value of peak in range of 0.50-2.20 ppm when (co) polymer (B) is dissolved in deuterated chloroform and 1H-NMR is measured, with solvent peak at 7.24 ppm based on CHCI3 in deuterated chloroform as reference. (b-2) the weight-average molecular weight as determined by GPC is 1,500-20,000, and (b-3) the melting point as determined by DSC is not observed in the temperature range of 100-150 DEG C.

Description

technical field [0001] One embodiment of the present invention relates to a resin composition, a molded article, a fiber, a film, and a sheet. Background technique [0002] Polyolefin-based resins such as polypropylene and polyethylene are thermoplastic general-purpose resins that are inexpensive and have many excellent physical properties such as moldability, chemical resistance, weather resistance, water resistance, and mechanical and electrical properties. Taking advantage of these characteristics, its injection molded products, extrusion molded products, compression molded products, etc. have been used in a wide range of fields such as food containers, automotive materials, electrical appliance casings, building materials, etc. as sheets, films, and molded products. [0003] However, polyolefin resin alone cannot obtain satisfactory physical properties, and it is not uncommon for polyolefin resins to be used as polyolefin alloys containing two or more components. [000...
