Description

  The present invention relates to a catalyst component for olefin polymerization, a catalyst for olefin polymerization containing the component, a method for producing an olefin polymer using the catalyst, and an olefin polymer produced by the method. Olefin polymerization catalyst component containing two types of metallocene compounds and a compound that reacts with the metallocene compound to form a cationic metallocene compound, an olefin polymerization catalyst containing the component, and a method for producing an olefin polymer using the catalyst And an olefin polymer or an ethylene polymer produced by the method.

  Polyolefins produced with metallocene catalysts for olefin polymerization have high polymer molecular structure such as molecular weight distribution and copolymer composition distribution, and are excellent in various mechanical properties such as impact strength and long life. The amount is increasing. However, metallocene-based polyolefins are excellent in mechanical properties, but because of their narrow molecular weight distribution, they are inferior in polyolefin molding important properties such as melt tension and melt fluidity, and have sufficient performance on the molding surface. It did not meet.

As a method of improving the molding processability of such an insufficient metallocene-based polyolefin, a method of improving the melt characteristics by blending metallocene-based polyolefins having different molecular weight distributions produced separately to broaden the molecular weight distribution (for example, Patent Document 1), high pressure method low density polyethylene (HPLD) excellent in melt properties, blended with metallocene polyolefin and modified (for example, see Patent Document 2), and wide by multistage polymerization using metallocene catalyst A method for producing a metallocene polyolefin having a molecular weight distribution (for example, see Patent Document 3) is known.
However, the method of broadening the molecular weight distribution by blending metallocene polyolefins with different molecular weight distributions is technically simple, but if the difference in the molecular weight of the blended polyolefin becomes large, it is difficult to mix sufficiently uniformly. Production costs associated with inventory management and extruder operation in production planning due to problems in appearance of products such as gels and fish eyes, deterioration of mechanical properties due to widening of molecular weight distribution, and a blending process. There is a problem that becomes high.

  The method of blending HPLD is also technically simple, but the molecular weight and density of available HPLD are only in a limited range. Problems such as limited to an extremely narrow range, unsuitable for modifying polyolefins that are not very compatible with HPLD, such as high-density polyethylene, and a decrease in mechanical strength due to blending of HPLD cannot be ignored There is.

  Although the method of broadening the molecular weight distribution by multistage polymerization is cheaper than the method by blending, it requires construction costs and operation management costs to connect and use a plurality of polymerization reactive groups. There is a problem that the mechanical properties are lowered due to the spreading, and further, the molecular weight distribution, that is, the mechanical properties of the polyolefin and the design freedom of the molding processability are limited by the size of each reactive group.

  On the other hand, as a method for improving the molding processability of insufficient metallocene-based polyolefins, flowability and melt tension are increased by introducing long chain branches into polyethylene by a polymerization reaction using a specific metallocene complex to increase melt viscosity. The method of improving is well known (for example, refer patent document 4). As a specific metallocene complex for introducing a long chain branch, a method using a bridged bisindenyl complex (for example, see Patent Documents 5 to 8) or a geometrically constrained half metallocene complex (for example, see Patent Document 9) is well known. However, the long chain branches obtained by these methods are not as developed as the HPLD structure, and the melt viscosity of the polymer is not sufficiently improved.

Further, as a method for introducing a long chain branch by a metallocene complex other than the above, a method for producing polyethylene containing a long chain branch using a bridged metallocene catalyst having a specific structure (for example, see Patent Document 10) is known. Specifically, an example in which two types of metallocene complexes of dimethylsilylbis (pentadienyl) zirconium dichloride complex and diphenylmethylene (cyclopentadienyl) (fluorenyl) zirconium dichloride complex are used simultaneously is introduced. As an improved technique, a catalyst in which the above two types of complexes are co-supported on the same carrier (for example, see Patent Documents 11 to 13) and a catalyst in which the types of complexes to be combined are improved (for example, Patent Document 14). Reference 15) is known. In these methods, one type of complex generates a polymer containing a polymerizable double bond at the terminal (so-called macromer), and the other complex is a complex having excellent copolymerizability, and the macromer is copolymerized. Thus, it is said to form a long-chain branched structure.
However, these methods also introduce a branched structure that is somewhat developed compared to the long-chain branched structure of the conventional metallocene complex, but the level is still insufficient, or the above two types of metallocene complexes are comonomer copolymerizable Therefore, there is a problem that the copolymer composition distribution of the produced polymer is widened and the mechanical properties are deteriorated due to the production of the low melting point polymer.

  Under these circumstances, in order to eliminate the problems of long-chain branched polyethylenes in the prior art and to improve the molding processability of metallocene polyethylene, metallocene polyethylene introduced with a sufficient number and appropriate length of long-chain branches Development of a catalyst component for olefin polymerization and a catalyst for polymerization for the production of olefin, and a method for producing an olefin polymer using the catalyst component has been desired.

The molar ratio of the essential component (A-1) which is the metallocene compound (A) and the essential component (A-2) is set within an arbitrary range depending on the material characteristics required for the olefin polymer which is the final product. In general, when the total of both is 100, it is 1:99 to 99.9: 0.1, preferably 5:95 to 99.5: 0.5, more preferably 10:90 to 99.5: 0.5, more preferably 20:80 to 99.5: 0.5, and particularly preferably 40:60 to 99.2: 0.8. When the component (A-1) is less than 1, the amount of macromer produced is insufficient and long chain branching is not sufficiently formed, so that improvement in molding processability is not seen in the product olefin polymer, or higher molecular weight. Since the component (A-2) that generates the polymer is the main active species, polymerization is required under conditions where there is a large amount of hydrogen as the molecular weight regulator, that is, disadvantageous for long-chain branching. It is not preferable because improvement in processability is not observed, or the polymer produced from a small amount of the component (A-1) has a lower molecular weight and the product is easily sticky. On the other hand, when the amount of component (A-1) is more than 99.9, it is difficult to sufficiently increase the molecular weight of the produced polymer, or long chain branching does not develop to a sufficiently high molecular weight, and improvement in molding processability is observed. It is not preferable because it is not possible. However, the molar ratio of the component (A-1) and the component (A-2) varies depending on whether the olefin polymerization activity of the two is largely different from the case of the same level. Needless to say, the material properties of the olefin polymer should be optimized.

When an organoaluminum oxy compound is used as the compound (B) that reacts with the metallocene compound (A) to form a cationic metallocene compound, the aluminum of the organoaluminum oxy compound relative to the transition metal (M) in the metallocene compound (A) is used.

The catalyst for olefin polymerization can be obtained as a solid catalyst by bringing them into contact with each other and then removing the solvent. The removal of the solvent is desirably performed under normal pressure or reduced pressure at 0 to 200 ° C., preferably 20 to 150 ° C. for 1 minute to 50 hours, preferably 10 minutes to 10 hours.

The olefin polymerization catalyst can also be obtained by the following method.

In the case of the contact methods (IV) and (V), the same conditions as described above can be used for the component ratio, contact conditions, and solvent removal conditions.

The olefin polymerization catalyst thus obtained may be used after the prepolymerization of the monomer if necessary.

6). Properties (characteristics) of olefin polymers and ethylene polymers
By the polymerization method of the present invention, an olefin polymer or ethylene polymer as described below is obtained. Here, the ethylene polymer will be mainly described. In the present invention, the ethylene polymer means an ethylene homopolymer or an ethylene / α-olefin copolymer produced by the above-mentioned copolymerization.
The density of the ethylene-based polymer produced by the production method of the ethylene polymer of the present invention is a 0.85~0.98g / cm ^3, preferably 0.88~0.97g / cm ^3, more preferably the 0.900~0.960g / cm ^3, more preferably 0.900~0.950g / cm ^3, particularly preferably 0.900~0.940g / cm ^3, and most preferably 0.900~0.930g / Cm ³ . MFR (melt flow rate, 190 ° C., 2.16 kg load) is 0.001 to 1000 g / 10 min, preferably 0.01 to 100 g / 10 min, more preferably 0.05 to 50 g / 10 min. More preferably, it is 0.10-10 g / 10min, Most preferably, it is 0.15-5.0g / 10min, Most preferably, it is 0.2-2.0g / 10min.

And the ethylene polymer manufactured by this invention is the big characteristic that melt property is improved with respect to a normal ethylene polymer, and has the outstanding moldability.
In general, polyethylene is processed into an industrial product by a molding method that passes through a molten state such as film molding, blow molding, foam molding, etc., but at this time, the elongational flow characteristics have a great influence on the ease of moldability. Giving is well known.
That is, polyethylene having a narrow molecular weight distribution and no long chain branching has poor moldability due to its low melt strength, whereas polyethylene having an ultrahigh molecular weight component or a long chain branching component is strain-hardened (strain Hardening), that is, polyethylene having a characteristic that the extensional viscosity rapidly increases on the high strain side, and polyethylene that exhibits this characteristic remarkably is said to be excellent in moldability.

  As a method for quantitatively expressing this extensional viscosity characteristic, there is a method for calculating the ratio of the extensional viscosity before strain hardening and the extensional viscosity after strain hardening as the strain hardening degree (λmax), which is an index representing the nonlinearity of the extensional viscosity. Useful as. When this λmax value is large, for example, there is an effect of preventing uneven thickness and blow-through of the product in film molding and blow molding, enabling high-speed molding, and increasing the closed cell ratio during foam molding. Advantages such as improved product strength, improved design, lighter weight, improved molding cycle, and improved heat insulation can be obtained.

  The ethylene-based polymer produced in the present invention has extremely characteristic elongational viscosity characteristics, molecular weight distribution, and intrinsic viscosity characteristics based on its characteristic long chain branched structure, and the following conditions (i) to (iv) It is preferable to have at least one of the specified characteristics because the molding process characteristics and mechanical properties such as rigidity, impact strength, and transparency are excellent. That is,

Condition (i): logarithmic plot of elongational viscosity η (t) (unit: Pa · second) and elongation time t (unit: second) measured at a temperature of 170 ° C. and an elongation strain rate of 2 (unit: 1 / second) When an inflection point of elongation viscosity due to strain hardening is observed, the maximum elongation viscosity after strain hardening is η _Max (t ₁ ), and the approximate straight line of elongation viscosity before curing is η _Linear (t) , Η _Max (t ₁ ) / η _Linear (t ₁ ), the strain hardening degree (λmax (2.0)) defined by 1.2 to 20. Here, the approximate straight line of the extension viscosity before curing is a tangent having the smallest inclination among the tangents of the curve of the log-log graph within the range of t corresponding to the strain amount of 0.2 to 1.0 ( However, the slope is 0 or a positive value).

  Condition (ii): Ratio λmax (2) between λmax (2.0) defined in the above condition (i) and λmax (0.1) when the elongation strain rate is 0.1 (unit: 1 / second) 0.0) / λmax (0.1) is 1.2-10.

Condition (iii): The branching index (g _C ′) at a molecular weight of 1,000,000 measured by a GPC measuring apparatus combining a differential refractometer, a viscosity detector, and a light scattering detector is 0.30 to 0.70. .

Condition (iv): The content (W _C ) of a component having a molecular weight of 1,000,000 or more measured by the GPC measuring apparatus described in the above condition (iii) is 0.01 to 30%.

The ethylene polymer produced in the present invention preferably has a λmax (2.0) of 1.2 to 20. λmax (2.0) is a characteristic value depending on the MFR of the ethylene polymer, and as the MFR increases, the value tends to increase. However, the ethylene polymer produced in the present invention has a small MFR. In spite of this, it has a great feature in having a high λmax (2.0). That is, λmax (2.0) is preferably 1.5 to 15, more preferably 1.7 to 10, and more preferably 1.9 to 8.0 when 0.01 ≦ MFR ≦ 2. Yes, particularly preferably 2.0 to 8.0, 2 <MFR ≦ 20, 1.8 to 18, more preferably 3.0 to 15, still more preferably 4.0 to 15, Most preferably, it is 5.0-15.
If λmax (2.0) is less than 1.2, the flowability and melt tension of the ethylene-based polymer become insufficient, and the molding process characteristics deteriorate. When λmax (2.0) is larger than 20, it is excellent in fluidity and melt tension, but it is preferable because the impact strength of the polyethylene resin composition and the molded article is lowered or transparency is deteriorated. I can not say. A detailed method for measuring λmax (2.0) will be described later.

The ethylene polymer produced in the present invention preferably has a λmax (2.0) / λmax (0.1) of 1.2 to 10. Like λmax (2.0), λmax (2.0) / λmax (0.1) is a characteristic value that depends on the MFR of the ethylene polymer, and the value tends to increase as the MFR increases. However, the ethylene-based polymer produced in the present invention is characterized by having a high λmax (2.0) / λmax (0.1) despite a small MFR. That is, λmax (2.0) / λmax (0.1) is preferably 1.3 to 8.0, more preferably 1.5 to 6.0 when 0.01 ≦ MFR ≦ 2. More preferably, it is 1.7-5.0, Most preferably, it is 1.8-4.0, In 2 <MFR <= 20, it is 1.7-10, More preferably, it is 1.9-9.0 More preferably, it is 2.0-8.0, Most preferably, it is 2.2-7.0.
If λmax (2.0) / λmax (0.1) is less than 1.2, the flowability and melt tension of the ethylene-based polymer become insufficient, and the molding process characteristics deteriorate. If λmax (2.0) / λmax (0.1) is greater than 10, it is excellent in fluidity and melt tension, but it is not preferable because impact strength decreases and transparency deteriorates.

Regarding the method for measuring the strain hardening degree, as long as the uniaxial extensional viscosity can be measured, the same value can be obtained in principle by any method. For example, the measurement method and the measuring instrument are disclosed in the known document: Polymer 42 (2001) 8663 Details are described.
In the measurement of the ethylene-based polymer according to the present invention, preferred measurement methods and measuring instruments include the following.

Measuring method:
・ Device: Ales manufactured by Rheometrics
-Jig: EXTENSIONAL VISUALITY FIXTURE, manufactured by TA Instruments
・ Measurement temperature: 170 ℃
-Strain rate: 2 / sec-Preparation of test piece: Press-molded to produce a sheet of 18 mm x 10 mm and a thickness of 0.7 mm.

Calculation method:
The elongational viscosity at 170 ° C. and a strain rate of 2 / second is plotted as a log-log graph of time t (second) on the horizontal axis and elongation viscosity η (Pa · second) on the vertical axis. On the log-log graph, the maximum elongation viscosity until strain is 4.0 after strain hardening is η _Max (t ₁ ) (t ₁ is the time when the maximum elongation viscosity is shown), A value calculated as η _Max (t ₁ ) / η _Linear (t ₁ ) is defined as a strain hardening degree (λmax), where η _Linear (t) is an approximate straight line of elongational viscosity. The presence / absence of strain hardening is determined by whether or not there is an inflection point at which the extensional viscosity changes from an upward convex curve to a downward convex curve over time.
1 and 2 are typical plots of elongational viscosity. FIG. 1 shows a case where an inflection point of elongational viscosity is observed, and η _Max (t ₁ ) and η _Linear (t) are shown in the figure. FIG. 2 shows a case where an inflection point of elongational viscosity is not observed.

The ethylene-based polymer produced in the present invention preferably has a branching index (g _C ′) of 0.30 to 0.70 in addition to the above conditions (i) and (ii) regarding the extensional viscosity characteristics, More preferably, it is 0.35-0.65, More preferably, it is 0.35-0.60, Most preferably, it is 0.35-0.50, Moreover, the component of molecular weight 1 million or more is suitable. Content (W _C ) is 0.01 to 30%, more preferably 0.1 to 20%, still more preferably 0.2 to 10%, and particularly preferably 0.3 to 6.%. 0%.
If the g _C ′ value is greater than 0.70, it cannot be said that the ethylene-based polymer has insufficient molding processability or insufficient transparency. If the g _C ′ value is less than 0.30, the moldability of the ethylene polymer is improved, but it is not preferable because the impact strength is lowered or the transparency is deteriorated. Even within g C _'value is preferably in the range, if W _C value is greater than 30%, too low melt fluidity, not preferable than hindered molding. In the present invention, W _C value and g _C of the ethylene-based polymer _'values, the molecular weight distribution curve or the branching index calculated from the GPC-VIS measurements following (g' long chain branching of evaluation method using) It is.
W or a _C value is insufficient moldability than 0.01% and an ethylene-based polymer, or insufficient mechanical strength, is not preferable because if the transparency or insufficient . W and _C value is greater than 30%, impact strength may decrease of the molded article, it can not be said preferable because the transparency is deteriorated. Even within W _C value is preferably in the range, if g C _'value is larger than 0.70, too low melt fluidity, not preferable than hindered molding.

[Branch structure analysis by GPC-VIS]
Waters Alliance GPCV2000 was used as a GPC apparatus equipped with a differential refractometer (RI) and a viscosity detector (Viscometer). In addition, as a light scattering detector, a DAWN-E manufactured by Wyatt Technology, a multi-angle laser light scattering detector (MALLS) was used. The detectors were connected in the order of MALLS, RI, and Viscometer. The mobile phase solvent is 1,2,4-trichlorobenzene (added with the antioxidant Irganox 1076 at a concentration of 0.5 mg / mL). The flow rate is 1 mL / min. As a column, two Tosoh Corporation GMHHR-H (S) HT were connected and used. The temperature of the column, sample injection section, and each detector is 140 ° C. The sample concentration was 1 mg / mL. The injection volume (sample loop volume) is 0.2175 mL. In order to obtain the absolute molecular weight (M) obtained from MALLS, the radius of inertia (Rg), and the intrinsic viscosity ([η]) obtained from Viscometer, data processing software ASTRA (version 4.73.04) attached to MALLS was used. The calculation was performed with reference to the following documents.

[Calculation of branching index (g _C '), etc.]
The branching index (g ′) is calculated as a ratio (ηbranch / ηlin) between the intrinsic viscosity (ηbranch) obtained by measuring the sample with the above Viscometer and the intrinsic viscosity (ηlin) obtained separately by measuring a linear polymer. To do.
When long chain branching is introduced into a polymer molecule, the radius of inertia is reduced compared to a linear polymer molecule of the same molecular weight. Since the intrinsic viscosity decreases as the inertia radius decreases, the ratio (ηbranch / ηlin) of the intrinsic viscosity (ηbranch) of the branched polymer to the intrinsic viscosity (ηlin) of the linear polymer having the same molecular weight decreases as long chain branching is introduced. It will become. Therefore, when the branching index (g ′ = ηbranch / ηlin) is smaller than 1, it means that a branch is introduced, and the introduced long chain branching increases as the value decreases. Means that. In particular, in the present invention, the absolute molecular weight obtained from MALLS is the content ratio (%) of the component having a molecular weight of 1 million or more to the total component amount measured by RI, and the content (W _C ) of the component having a molecular weight of 1 million or more. As the absolute molecular weight obtained from MALLS, the above g ′ at a molecular weight of 1,000,000 is calculated as g _C ′.
FIG. 4 shows an example of the analysis result by the GPC-VIS. The left side of FIG. 4 shows the molecular weight distribution curve measured based on the molecular weight (M) obtained from MALLS and the concentration obtained from RI, and the right side of FIG. 4 shows the branching index (g ′) at the molecular weight (M). . Here, linear polyethylene Standard Reference Material 1475a (National Institute of Standards & Technology) was used as the linear polymer.
