Description

  The present invention provides a novel ethylene polymer resin composition excellent in moldability and mechanical strength as compared with conventionally known ethylene polymers or ethylene polymer resin compositions, and ethylene polymers More specifically, the present invention relates to a thermoplastic resin composition containing a resin composition, and more particularly to a molded article, preferably a film, comprising the ethylene polymer resin composition and a thermoplastic resin composition containing the ethylene polymer resin composition. .

Ethylene polymers are molded by various molding methods and are used for various purposes. Depending on these molding methods and applications, the properties required for the ethylene-based polymer also differ. For example, when a cast film is to be formed in T-die molding, a neck-in in which the film end portion shrinks in the center direction occurs. When neck-in occurs, the film width decreases and the thickness of the film end increases compared to the center of the film, resulting in poor product yield. In order to minimize the neck-in, it is necessary to select an ethylene polymer having a high melt tension for the molecular weight. Similar properties are necessary to prevent sagging or tearing in hollow molding, or to prevent bubble swaying or tearing in blown film.

  High-pressure low-density polyethylene is used for applications such as films and hollow containers because of its high melt tension and good moldability compared to ethylene polymers produced using Ziegler catalysts. However, high-pressure low-density polyethylene is expected to be inferior in mechanical strength such as tensile strength, tear strength or impact strength because it has a complicated long-chain branched structure. For the same reason, it is expected that the high-speed film forming processability in T-die molding is inferior.

  Also, among Ziegler catalyst systems, ethylene polymers obtained using metallocene catalyst systems are excellent in mechanical strength such as tensile strength, tear strength or impact strength, but have a large neck-in due to inferior melt tension. Degradation of moldability is expected.

  As an ethylene polymer having good moldability and excellent mechanical strength, a composition of an ethylene polymer obtained by using a high-pressure low-density polyethylene and a metallocene catalyst system is disclosed in, for example, JP-A-6-65443. Proposed. However, when the content of the high-pressure method low-density polyethylene is small, the melt tension is not sufficiently improved, so that the moldability is expected to deteriorate such as a large neck-in in T-die molding. Further, when the content of the high-pressure method low-density polyethylene is large, it is expected that the mechanical strength such as tensile strength, tear strength or impact strength is inferior.

In order to solve such a problem, various ethylene polymers into which long chain branches are introduced have been disclosed. JP-A-2-276807 discloses an ethylene polymer obtained by solution polymerization in the presence of a catalyst comprising ethylenebis (indenyl) hafnium dichloride and methylalumoxane, and JP-A-4-213309 discloses a silica. An ethylene polymer obtained by gas phase polymerization in the presence of a catalyst composed of ethylenebis (indenyl) zirconium dichloride and methylalumoxane supported on a catalyst is disclosed in WO 93/08221 as a solution in the presence of a constrained geometric catalyst. An ethylene polymer obtained by polymerization is disclosed in JP-A-8-311260 as a catalyst comprising a racemic and meso isomer of Me ₂ Si (2-Me-Ind) ₂ supported on silica and methylalumoxane. An ethylene polymer obtained by gas phase polymerization in the presence of a chemically treated montmorillonite is disclosed in JP-A-8-34819. JP-A-8-319313 discloses an ethylene polymer obtained by slurry polymerization in the presence of a catalyst comprising bis (cyclopentadienyl) zirconium dichloride supported on Cp * Ti (OMe) ₃ and methylalumone. An ethylene-based polymer obtained by polymerization using a catalyst comprising xane is disclosed.

  There is a description that these ethylene-based polymers have improved melt tension and excellent moldability compared to straight-chain ethylene polymers without long-chain branching, but the neck-in is still greatly improved for improving moldability. Is expected to be insufficient.

  In addition, an ethylene polymer into which a small amount of a high molecular weight component is introduced in order to improve moldability is disclosed.

  JP-A-6-172594 discloses an ethylene resin composition comprising a high molecular weight component and a low molecular weight component, obtained using a Ziegler catalyst. Since this ethylene-based resin composition has a too high molecular weight, moldability is expected to be poor. Moreover, since the Ziegler catalyst that is a multi-site catalyst is used, the composition distribution is expected to be wide.

  JP-A-11-166083 discloses an ethylene resin composition comprising an ethylene polymer comprising a high molecular weight component and a low molecular weight component obtained using a Ziegler catalyst, and an ethylene polymer obtained using a Phillips catalyst. Is disclosed. This ethylene-based resin composition is expected to be inferior in low-temperature sealability because the density is too high. Moreover, it is known that the ethylene polymer obtained using a Philips catalyst has many terminal vinyl groups. Therefore, this ethylene resin composition is expected to be inferior in thermal stability. Furthermore, since a Ziegler catalyst that is a multi-site catalyst is used, the composition distribution is expected to be wide.

  As described above, it has been difficult to efficiently obtain a resin excellent in moldability and mechanical strength from the conventional known techniques. In other words, if an ethylene polymer having excellent moldability and mechanical strength appears, it can be said that its industrial value is extremely large.

As a result of intensive studies in view of such a situation, the present inventors have given a specific molecular structure and melt properties, so that the neck-in in T-die molding is small, excellent in high-speed film forming workability, and mechanical. An ethylene polymer having excellent strength has been found. However, when such an ethylene polymer is subjected to T-die molding at high speed, the film is likely to have thickness unevenness called surging, and as a result, the mechanical strength may vary from place to place. Therefore, as a result of further research, an ethylene polymer resin composition obtained by blending this ethylene polymer with a low density polyethylene obtained by a high pressure radical polymerization method is excellent in moldability, that is, T It has been found that the neck-in in die molding is small, surging does not occur even under high-speed molding, and the obtained film is excellent in mechanical strength, and the present invention has been completed.

The low-density polyethylene produced by the high-pressure radical method.

  By blending the ethylene polymer resin composition according to the present invention with another resin, a thermoplastic resin composition having excellent moldability and mechanical strength can be obtained. By processing the ethylene polymer resin composition according to the present invention and the resin composition containing the ethylene polymer resin composition, a molded body, preferably a film, excellent in moldability and mechanical strength is obtained. can get.

  The ethylene-based polymer resin composition of the present invention and the thermoplastic resin composition containing the ethylene-based polymer resin composition have good moldability and a molded product excellent in mechanical strength, preferably a film. Can do.

  Hereinafter, the ethylene polymer resin composition according to the present invention will be specifically described. The ethylene polymer resin composition of the present invention comprises an ethylene polymer [A] and a high pressure method low density polyethylene [B].

★ Ethylene polymer [A]
The ethylene polymer [A] constituting the ethylene polymer resin composition according to the present invention includes ethylene and an α-olefin having 4 to 10 carbon atoms, preferably ethylene and an α-olefin having 4 to 10 carbon atoms ( However, when butene-1 is used as a comonomer, an α-olefin having 6 to 10 carbon atoms is also essential), and more preferably a copolymer of ethylene and an α-olefin having 6 to 10 carbon atoms. Examples of the α-olefin having 4 to 10 carbon atoms used for copolymerization with ethylene include 1-butene, 1-hexene, 4-methyl-1-pentene, 1-octene and 1-decene.

Such an ethylene polymer has the characteristics shown in the following [A1] to [A4].
[A1] The melt flow rate (MFR) is in the range of 1.0 to 50 g / 10 minutes, preferably 2.0 to 50 g / 10 minutes, more preferably 4.0 to 50 g / 10 minutes. When the melt flow rate (MFR) is 1.0 g / 10 min or more, the shear viscosity of the obtained ethylene polymer is not too high and the moldability is good. When the melt flow rate (MFR) is 50 g / 10 min or less, the resulting ethylene polymer has good tensile strength.

  The melt flow rate (MFR) strongly depends on the molecular weight. The smaller the melt flow rate (MFR), the larger the molecular weight, and the larger the melt flow rate (MFR), the smaller the molecular weight. Further, it is known that the molecular weight of an ethylene polymer is determined by the composition ratio of hydrogen and ethylene (hydrogen / ethylene) in the polymerization system (for example, Kazuo Soga, KODANSHA “CATALYTIC OLEFIN POLYMERIZATION”, p376 (1990)). For this reason, by increasing / decreasing hydrogen / ethylene, it is possible to produce an ethylene polymer having a melt flow rate (MFR) at the upper limit / lower limit of the claims.

  Melt flow rate (MFR) is measured under conditions of 190 ° C. and 2.16 kg load according to ASTM D1238-89.

[A2] The density (d) is in the range of 890 to 950 kg / m ³ , preferably 900 to 940 kg / m ³ , more preferably 905 to 935 kg / m ³ . When the density (d) is 890 kg / m ³ or more, the resulting ethylene polymer has good heat resistance, and when the density (d) is 950 kg / m ³ or less, the resulting ethylene polymer has a low temperature sealing property. Is good.

  The density depends on the α-olefin content of the ethylene polymer. The smaller the α-olefin content, the higher the density, and the higher the α-olefin content, the lower the density. It is also known that the α-olefin content in an ethylene polymer is determined by the composition ratio of α-olefin and ethylene (α-olefin / ethylene) in the polymerization system (for example, Walter Kaminsky, Makromol). Chem. 193, p.606 (1992)). For this reason, it is possible to produce an ethylene polymer having the density of the lower limit / upper limit of the claims by increasing / decreasing α-olefin / ethylene.

  The density (d) was measured with a density gradient tube after heat-treating the measurement sample at 120 ° C. for 1 hour and linearly cooling to room temperature over 1 hour.

[A3] The ratio [MT / η ^* (g / P)] of the melt tension [MT (g)] to the shear viscosity [η ^* (P)] at 200 ° C. and an angular velocity of 1.0 rad / sec is 1.50. × 10 ^{−4 to} 9.00 × 10 ⁻⁴ , preferably 2.30 × 10 ^{−4 to} 9.00 × 10 ⁻⁴ , more preferably 3.00 × 10 ^{−4 to} 9.00 × 10 ⁻⁴ . It is a range. When MT / η * is 1.50 × 10 ⁻⁴ or more, the resulting ethylene polymer has good neck-in.

MT / η ^* is the ratio of the molecular weight of the ethylene polymer polymerized in the <previous stage> to the molecular weight of the ethylene polymer polymerized in the <follower stage> in the production method shown in Example 1 ( <Previous stage> molecular weight / <follower stage> molecular weight), and MT / η ^* increases as the <previous stage> molecular weight / <lower stage> molecular weight increases, and MT / η ^* increases as the <previous stage> molecular weight / <follower stage> molecular weight decreases. ^* Becomes smaller. Further, it is known that the molecular weight of an ethylene polymer is determined by the composition ratio (hydrogen / ethylene) of hydrogen and ethylene in the polymerization system (for example, Kazuo Soga, KODANSHA “CATALYTIC OLEFIN POLYMERIZATION”, p376 ( 1990)). Therefore, by adjusting hydrogen / ethylene and increasing / decreasing the <previous stage> molecular weight / <follower stage> molecular weight, it is possible to produce an ethylene polymer having MT / η ^* of the upper and lower limits of the claims. .

  The melt tension (MT) is determined by measuring the stress when the molten polymer is stretched at a constant rate. For the measurement, an MT measuring machine manufactured by Toyo Seiki Seisakusho was used. The conditions were a resin temperature of 190 ° C., a melting time of 6 minutes, a barrel diameter of 9.55 mmφ, an extrusion speed of 15 mm / min, a winding speed of 10 to 20 m / min, a nozzle diameter of 2.095 mmφ, and a nozzle length of 8 mm.

Further, the shear viscosity (η ^* ) at 200 ° C. and the angular velocity of 1.0 rad / sec is the angular velocity [ω (rad / sec)] dispersion of the shear viscosity (η ^* ) at the measurement temperature of 200 ° C. of 0.02512 ≦ ω ≦ 400. It is determined by measuring in the range. A rheometer RDS-II manufactured by Rheometrics was used for the measurement. The sample holder was a 25 mmφ parallel plate, and the sample thickness was about 1.8 mm. The number of measurement points was 5 per ω digit. The amount of strain was appropriately selected within a range of 10 to 30% so that the torque in the measurement range could be detected and torque was not exceeded. The sample used for the shear viscosity measurement was a press-molding machine manufactured by Shinfuji Metal Industry Co., Ltd., preheating temperature 190 ° C., preheating time 5 minutes, heating temperature 190 ° C., heating time 2 minutes, heating pressure 100 kg / cm ² , cooling temperature 20 The measurement sample was prepared by press molding to a thickness of 2 mm under the conditions of a cooling pressure of 100 kg / cm ² at 5 ° C. and a cooling time of 5 minutes.

[A4] The sum of the number of methyl branches [A (/ 1000C)] and the number of ethyl branches [B (/ 1000C)] [(A + B) (/ 1000C)] measured by ¹³ C-NMR is 1.4. Hereinafter, it is preferably 1.0 or less, more preferably 0.6 or less. The number of methyl branches and the number of ethyl branches defined in the present invention are defined as a number per 1000 carbons as described later.

  If there are short chain branches such as methyl branch and ethyl branch in the ethylene-based polymer, the short chain branch is incorporated into the crystal and the interplanar spacing of the crystal widens, which may reduce the mechanical strength of the resin. It is known (for example, Zenjiro Osawa et al .: Life prediction and longevity technology of polymer, p.481, NTS (2002)). Therefore, when the sum of the number of methyl branches and the number of ethyl branches (A + B) is 1.4 or less, the resulting ethylene polymer has good mechanical strength.

  The number of methyl branches and the number of ethyl branches in the ethylene polymer strongly depend on the polymerization method of the ethylene polymer, and the ethylene polymer obtained by high pressure radical polymerization is obtained by coordination polymerization using a Ziegler type catalyst system. Compared to the obtained ethylene polymer, the number of methyl branches and the number of ethyl branches are large. In the case of coordination polymerization, the number of methyl branches and the number of ethyl branches in the ethylene polymer strongly depend on the composition ratio of propylene, 1-butene and ethylene (propylene / ethylene, 1-butene / ethylene) in the polymerization system. To do. Therefore, by increasing or decreasing 1-butene / ethylene, it is possible to produce an ethylene polymer having the sum of the number of methyl branches and the number of ethyl branches (A + B) in the claims.

^The number of methyl branches and the number of ethyl branches measured by ¹³ C-NMR are determined as follows. The measurement was carried out using an ECP500 type nuclear magnetic resonance apparatus (1H: 500 MHz) manufactured by JEOL Ltd. at a cumulative number of 10,000 to 30,000. The main chain methylene peak (29.97 ppm) was used as the chemical shift standard. In a commercial NMR measurement quartz glass tube with a diameter of 10 mm, PE sample 250 to 400 mg and Wako Pure Chemical Industries, Ltd. special grade o-dichlorobenzene: ISOTEC benzene-d6 = 5: 1 (volume ratio) 3 ml of the mixed solution was added, and the mixture was heated at 120 ° C. and uniformly dispersed. Assignment of each absorption in the NMR spectrum was carried out according to Chemical Domain No. 141 NMR-Review and Experiment Guide [I], pages 132-133. The number of methyl branches per 1,000 carbons was calculated from the integrated intensity ratio of the absorption of methyl groups derived from methyl branches (19.9 ppm) to the integrated sum of absorptions appearing in the range of 5 to 45 ppm. The number of ethyl branches was calculated from the integrated intensity ratio of the absorption (10.8 ppm) of ethyl groups derived from ethyl branches to the integrated sum of absorptions appearing in the range of 5 to 45 ppm.

  In addition to the above requirements, the ethylene polymer [A] constituting the ethylene polymer resin composition according to the present invention preferably satisfies any one or more of the following [a1] to [a3].

  [a1] The ratio (Mz / Mw) of the Z average molecular weight (Mz) and the weight average molecular weight (Mw) measured by GPC is 10 or more, preferably 20 or more, more preferably 30 or more. When Mz / Mw is 10 or more, the melt tension of the resulting ethylene-based polymer is increased and the moldability is excellent.

  Mz / Mw widens the difference between the molecular weight of the ethylene polymer polymerized in the <front stage> and the molecular weight of the ethylene polymer polymerized in the <back stage> in the production method shown in Example 1. It becomes large and becomes small when the difference is narrowed. Further, it is known that the molecular weight of an ethylene polymer is determined by the composition ratio (hydrogen / ethylene) of hydrogen and ethylene in the polymerization system (for example, Kazuo Soga, KODANSHA “CATALYTIC OLEFIN POLYMERIZATION”, p376 ( 1990)). For this reason, by adjusting hydrogen / ethylene, the molecular weight of the ethylene polymer polymerized in the <front stage> and the molecular weight of the ethylene polymer polymerized in the <back stage> are increased or decreased. It is possible to produce an ethylene-based polymer having Mz / Mw.

  The Z average molecular weight (Mz) and the weight average molecular weight (Mw) were measured as follows using GPC-150C manufactured by Waters. The separation columns were TSKgel GMH6-HT and TSKgel GMH6-HTL, the column size was 7.5 mm in inner diameter and 600 mm in length, the column temperature was 140 ° C., and o-dichlorobenzene (Wako Pure Chemical Industries) was used as the mobile phase. Industry) and BHT (Takeda Pharmaceutical) 0.025 wt% as an antioxidant, moved at 1.0 ml / min, sample concentration 0.1 wt%, sample injection volume 500 microliters, detector A differential refractometer was used. Standard polystyrenes used were those manufactured by Tosoh Corporation for molecular weights of Mw <1000 and Mw> 4 × 10 6, and those manufactured by Pressure Chemical Co. for 1000 <Mw <4 × 10 6. The molecular weight calculation is a value obtained by universal calibration and conversion as PE.

  [a2] Number of terminal vinyl groups per molecular chain (V) calculated from the number of terminal vinyl groups per 1000 carbon atoms measured by IR [v (/ 1000 C)] and the number average molecular weight (Mn) measured by GPC Is 0.47 / 1 molecular chain or less, preferably 0.30 / 1 molecular chain or less, more preferably 0.16 / 1 molecular chain or less. When the number of terminal vinyl groups per molecular chain (V) is 0.47 / 1 molecular chain or less, the resulting ethylene polymer is excellent in thermal stability during molding.

  The number of terminal vinyl groups per molecular chain (V) strongly depends on the composition ratio of hydrogen and ethylene in the polymerization system (hydrogen / ethylene). When hydrogen / ethylene is increased, the number of terminal vinyl groups per molecular chain ( V) decreases, and the number of terminal vinyl groups per molecular chain (V) increases when hydrogen / ethylene is decreased. For this reason, in the production method shown in Example 1, by increasing / decreasing hydrogen / ethylene in <previous stage>, an ethylene-based polymer having the number of terminal vinyl groups (V) per molecular chain as claimed is produced. It is possible.

  The number of terminal vinyl groups per molecular chain (V) is expressed by the following formula (Eq-3) using the number average molecular weight (Mn) measured by GPC and the number of terminal vinyl groups per 1000 carbon atoms (v) measured by IR. Determined by.

  The number average molecular weight (Mn) was measured by the same method as described above using GPC-150C manufactured by Waters.

The number of terminal vinyl groups per 1000 carbon atoms (v) was measured using an infrared spectrophotometer FT-IR 410 model manufactured by JASCO Corporation as follows. The sample to be measured is about 0.3 g of ethylene polymer sandwiched in the order of a Teflon (registered trademark) sheet (0.1 mm thick), an aluminum plate (0.1 mm thick), and an iron plate (2 to 3 mm thick), and this is heated with a hydraulic molding machine. temperature 180 ° C., the heating time of 3 minutes, pressed at a molding pressure 50 to 100 / cm ^2, then, was prepared by cooling for 1 minute, pressure 0~50kg / cm ² at room temperature. Measurements by transmission method, the measuring range 5000cm ^-1 ~400cm ^-1, resolution 2 cm ^-1, were carried out at accumulated number 4 times. From a calibration curve prepared using polyethylene derived from a terminal vinyl group detected at 910 cm −1 as a key band and containing no unsaturated bond, and polyethylene having all vinyl groups at one end, the number of carbon atoms was 1000 The number of terminal vinyl groups per unit (v (/ 1000 C)) was quantified.

  [a3] The maximum melting point peak [Tm (° C.)] and density (d) in DSC satisfy the following relational expression (Eq-1).

Preferably, the following relational expression (Eq-2) is satisfied

When the maximum peak (Tm) of the melting point is 0.315 × d-170 or less, the resulting ethylene polymer is excellent in low-temperature sealability.

  The maximum peak (Tm) of the melting point depends not only on the density (d) but also on the α-olefin distribution (composition distribution) between the molecular chains of the resulting ethylene polymer. When the density is the same, the wider the composition distribution, the smaller the molecular chain of α-olefin, and the formation of thick crystals. Therefore, the maximum peak (Tm) of the melting point becomes higher, and the narrower the composition distribution, the more the α-olefin. Since each molecular chain exists uniformly and does not form a thick crystal, the maximum peak (Tm) of the melting point is low. In the case of Ziegler catalysts, it is known that the composition distribution of the resulting ethylene polymer is wide due to heterogeneous active sites (for example, Kazuo Matsuura et al .: Polyethylene Technology Reader, p.20, Industrial Research Committee (2001 )). Therefore, when the density of the ethylene polymer is the same, the maximum peak (Tm) of the melting point becomes high. In the case of a metallocene catalyst, since the active sites are homogeneous, the resulting ethylene polymer composition distribution becomes narrow. As a result, when the density is the same, the maximum peak (Tm) of the melting point becomes low. The maximum melting point peak (Tm) at the same density can be varied depending on the polymerization temperature. If the polymerization temperature is raised, the inside of the polymerization system becomes uniform and the composition distribution tends to be narrow. As a result, the maximum peak (Tm) of the melting point at the same density is lowered. If the polymerization temperature is lowered, the inside of the polymerization system becomes non-uniform and the composition distribution tends to be broadened. As a result, the maximum peak (Tm) of the melting point at the same density is increased. Therefore, an ethylene polymer satisfying the relationship between the maximum peak (Tm) and the density (d) of the melting point in the claims by increasing / decreasing the polymerization temperature in <previous stage> in the production method shown in Example 1 Can be manufactured.

The maximum peak (Tm) of the melting point was measured as follows using Pyris 1 manufactured by PERKIN ELMER. The sample used for the measurement was a pre-heating temperature of 190 ° C., a pre-heating time of 5 minutes, a heating temperature of 190 ° C., a heating time of 2 minutes, a heating pressure of 100 kg / cm ² , a cooling temperature of 20 ° C. The measurement sample was prepared by press molding to a thickness of 2 mm under the condition of a cooling time of 5 minutes and a cooling pressure of 100 kg / cm ² . About 5 mg of a measurement sample was packed in an aluminum pan, and measurement was performed with the following temperature profiles [cond-1] to [cond-3] under a nitrogen atmosphere (nitrogen: 20 ml / min.).
[cond-1] Temperature increased from 30 ° C to 200 ° C at 10 ° C / min
[cond-2] Hold at 200 ° C for 5 minutes, then cool down to 30 ° C at 20 ° C / min
[cond-3] The temperature is increased from 30 ° C. to 200 ° C. at 10 ° C./min. The maximum peak temperature in the endothermic curve obtained by the measurement of [cond-3] did.
