Description

  The present invention relates to a catalyst component for addition polymerization classified as a single site catalyst, a catalyst for addition polymerization, and a method for producing an addition polymer.

Addition polymers such as polypropylene and polyethylene are widely used in various molding fields due to their excellent mechanical properties, chemical resistance, etc., and their excellent balance between properties and economy.
Conventionally, these addition polymers are a combination of a solid catalyst component obtained mainly using a Group 4 metal compound such as titanium trichloride or titanium tetrachloride and a Group 13 metal compound typified by an organoaluminum compound. It has been produced by polymerizing olefins and the like using a conventional solid catalyst (multisite catalyst).

  Unlike conventional solid catalyst components that have been used for a long time in recent years, transition metal components composed of transition metal compounds that can be isolated (for example, metallocene complexes and nonmetallocene compounds) and organometallic components composed of aluminoxanes, etc. A method for producing an addition polymer in which an olefin or the like is polymerized using a combined so-called single site catalyst has been proposed. For example, Patent Document 1 reports a method using bis (cyclopentadienyl) zirconium dichloride and methylaluminoxane. It has also been reported that certain boron compounds are combined with such transition metal compounds. For example, Patent Document 2 reports a method using bis (cyclopentadienyl) zirconium dimethyl and tri (n-butyl) ammonium tetrakis (pentafluorophenyl) borate. Addition polymers obtained using these single-site catalysts generally have a narrower molecular weight distribution than those obtained with conventional solid catalysts (multi-site catalysts), and in the case of copolymers, the comonomer is copolymerized more uniformly. Therefore, it is known that an addition polymer more homogeneous than that obtained when a conventional solid catalyst is used can be obtained. In addition, from the viewpoint of processability and physical properties of the resulting addition polymer, single site catalysts and polymerization methods that slightly reduce the homogeneity of the addition polymer are also known (Patent Documents 3 to 6).

  Since ordinary single-site catalysts are soluble in the reaction system, the shape of the resulting addition polymer is not suitable when applied to polymerization involving the formation of addition polymer particles (for example, slurry polymerization, gas phase polymerization, bulk polymerization, etc.). It may lead to formation of coarse and coarse addition polymer particles, bulk addition polymer, fine powder addition polymer, etc., reduction of the bulk density of the addition polymer, adhesion of the addition polymer to the polymerization reactor wall, and the like. And in such a case, there is a problem that these causes contribute to poor heat transfer, poor heat removal, etc., resulting in a state where stable operation is difficult, resulting in reduced productivity. It is known to use specific particles as one of the catalyst components (for example, Patent Document 7).

Incidentally, in the production of an addition polymer, the molecular weight of the resulting addition polymer is adjusted with hydrogen gas. That is, if a large amount of hydrogen is introduced into the polymerization system, the molecular weight generally decreases. From the viewpoint of design, it is preferable if a high molecular weight addition polymer can be obtained even in the presence of high concentration hydrogen, since the range of molecular weight design is widened.

The treatment time is usually 1 minute to 200 hours, preferably 10 minutes to 100 hours. Further, such treatment may use a solvent, or these compounds may be directly treated without using them.

  As the solvent, a solvent that does not react with each of the components to be contacted when the solvent is used and the contact product obtained by contact is usually used. As described above, when each component is brought into contact stepwise, for example, even if the solvent reacts with (a), contact obtained by contacting (a) with other components The product may no longer react with the solvent, and in such a case, the solvent can be used as a solvent in the contact operation using the contact product as one component.

  In the case of <2>, <5>, <6>, <8>, <9>, <10>, <11>, <12> above, a hydrocarbon solvent or an aromatic hydrocarbon solvent that is a nonpolar solvent Is more preferable. This is because the contact product between (a) and (c) or the contact product between (a) and (b) and (c) is generally soluble in a nonpolar solvent. Since it is low, when (d) is present in the reaction system when these contact products are produced, it is more stable that the produced contact product is deposited on the surface of (d) than in a nonpolar solvent. It is preferable because it is considered that the fixation becomes easier.

  The amount used when each compound is used again is the same as the amount used above.

  In the actual contact treatment of each compound, even if the use of each compound is intended to completely satisfy the above formula (1), the amount used may fluctuate slightly and remain unreacted. In consideration of the amount of the compound to be used, etc., it is usual to slightly increase or decrease the amount used as appropriate. Here, “substantially satisfying the formula (1)” is obtained by bringing each compound into contact with each other at a molar ratio satisfying the above formula (1) without completely satisfying the above formula (1). It is meant to be included when attempting to obtain such objects.

  In the preparation of the modified particles of the present invention, the amount of (d) used relative to (a) is derived from (a) contained in the particles obtained by contacting (a) and (d).

And may be determined as appropriate within the range.

  After the contact treatment as described above, heating is also preferably performed in order to further advance the reaction. In heating, it is preferable to use a solvent having a higher boiling point in order to obtain a higher temperature. Therefore, the solvent used for the contact treatment may be replaced with another solvent having a higher boiling point.

In general, the polymerization time is appropriately determined depending on the kind of the target olefin polymer and the reaction apparatus, but can be in the range of 1 minute to 20 hours.

The present invention is particularly suitably applied to polymerization involving formation of addition polymer particles (for example, slurry polymerization, gas phase polymerization, bulk polymerization, etc.).
The slurry polymerization may be performed according to a known slurry polymerization method and polymerization conditions, but is not limited thereto.

As a method for supplying each component to the polymerization tank, a solution or a slurry is usually supplied using an inert gas such as nitrogen or argon, hydrogen, ethylene or the like in the absence of moisture, or dissolved or diluted in a solvent. A method such as supplying in a state can be used. Each catalyst component may be supplied individually, or may be supplied by contacting arbitrary components in advance in an arbitrary order.

  As polymerization conditions, the temperature is less than the temperature at which the polymer melts, preferably 0 ° C. to 150 ° C., particularly preferably 30 ° C. to 100 ° C. Furthermore, hydrogen may be added as a molecular weight modifier for the purpose of adjusting the melt fluidity of the final product.
