Embodiment 1

[0144] An autoclave having an inner volume of 400 ml equipped with a stirrer was dried under vacuum and replaced with argon, 190 ml of cyclohexane as a solvent and 10 ml of 1-hexene as a comonomer were added, and the autoclave was heated to 70°C . After heating, add ethylene, while adjusting the pressure of ethylene to 6kg / cm 2 . After the system is stable, add 0.25 mmol triisobutylaluminum, continuously add 1.0 μmol ethylene bis(indenyl) zirconium dichloride, then add 86.5 mg (101 μmol) of complex A with the following structure, and start polymerization . Polymerization was allowed to proceed for 30 minutes.

[0145] As a result of the polymerization, 18.6 g of an ethylene-1-hexene copolymer was obtained. The polymerization activity is 3.7×10 7 g / mol / h, SCB was 19.37, [η] was 1.29 dl / g, Mw was 88000, and Mw / Mn was 2.6.

Embodiment 2

[0153] An autoclave having an inner volume of 400 ml equipped with a stirrer was dried under vacuum and replaced with argon, 190 ml of cyclohexane as a solvent and 10 ml of 1-hexene as a comonomer were added, and the autoclave was heated to 70°C . After heating, add ethylene, while adjusting the pressure of ethylene to 6kg / cm 2 . After the internal stabilization of the system, 0.25 mmol of triisobutylaluminum was added, and 77.1 mg (89.7 μmol) of complex A used in Example 1 was added continuously. After stirring for 30 minutes, 1.0 μmol of ethylenebis(indenyl)zirconium dichloride was added, and polymerization was carried out for 30 minutes.

[0154] As a result of the polymerization, 20.79 g of an ethylene-1-hexene copolymer was obtained. The polymerization activity is 4.2×10 7 g / mol / h.

Embodiment 3

[0156] Polymerization was performed in the same manner as in Example 1 except that 84.6 mg (97.7 μmol) of complex B having the following structure was used instead of complex A used in Example 1.

[0157] As a result, 2.46 g of an ethylene-1-hexene copolymer was obtained. The polymerization activity is 4.9×10 6 g / mol / h, [η] was 1.28dl / g, Mw was 73000, and Mw / Mn was 1.9.

[0158] Complex B:

[0159]

[0160] Manufactured by Aldrich Co., Ltd.

[0161] The orbital coefficient of the valence P-type atomic orbital is 0.773, and the orbital energy is 0.0049. Calculation was carried out in the same manner as complex A above.

Abstract

A catalyst component for addition polymerization containing (A) a compound containing an atom of the Group II to the Group XII or Lanthanide series in which the lowest energy level of unoccupied molecular orbital having the valence p-type atomic orbital of the atom of the Group II to the Group XII or Lanthanide series as a main component, wherein the coefficient represented by a linear combination, is 0.4 or more is calculated to be 0.008 atomic unit (Hartree) or less by the calculation of density functional method (B3LYP / 3-21G level), a catalyst for addition polymerization containing the same, and a process for producing an addition polymer with the catalyst are disclosed.

Description

technical field [0001] The present invention relates to polyaddition catalyst components, catalysts for polyaddition prepared using the components, and methods for preparing polyaddition polymers. Background technique [0002] Since olefin polymers such as polypropylene and polyethylene have good mechanical properties, chemical resistance, etc., and are relatively low in cost in view of these properties, they have been widely used in various molding processing fields. These olefin polymers are produced by polymerizing olefins using common solid catalysts (multi-site catalysts) obtained from metal compounds of Group IV such as titanium trichloride, titanium tetrachloride, etc. A component obtained by combining a Group XIII metal compound represented by an organoaluminum compound. [0003] Recently, a method for producing addition polymers has been proposed, which uses a so-called single-site catalyst to polymerize addition-polymerizable monomers, which is a solid catalyst di...
