[기술분야】  [Technical Field]
본 발명은 가공성이 우수한 올레핀계 중합체에 관한 것이다.  The present invention relates to an olefin polymer having excellent processability.
【발명의 배경이 되는 기술】  [Technique to become background of invention]
올레핀 중합 촉매계는지글러 나타 및 메탈로센 촉매계로 분류할 수 있으며, 이 두 가지의 고활성 촉매계는 각각의 특징에 맞게 발전되어 왔다. 지글러 나타 촉매는 50년대 발명된 이래 기존의 상업 프로세스에 널리 적용되어 왔으나, 활성점이 여러 개 흔재하는 다활성점 촉매 (multi site catalyst)이기 때문에, 중합체의 분자량 분포가 넓은 것이 특징이며, 공단량체의 조성 분포가 균일하지 않아 원하는 물성 확보에 한계가 있다는 문제점이 있다.  Olefin polymerization catalyst systems can be classified into Ziegler-Natta and metallocene catalyst systems, and these two highly active catalyst systems have been developed for their respective characteristics. The Ziegler-Natta catalyst has been widely applied to the existing commercial processes since the invention in the 50s, but is characterized by a wide molecular weight distribution of the polymer due to its multi-site catalyst having many active sites. There is a problem that there is a limit in securing the desired physical properties because the composition distribution is not uniform.
한편， 메탈로센 촉매는 전이금속 화합물이 주성분인 주촉매와 알루미늄이 주성분인 유기 금속 화합물인 조촉매의 조합으로 이루어지며, 이와 같은 촉매는 균일계 착체 촉매로 단일 활성점 촉매 (single site catalyst)이며, 단일 활성점 특성에 따라 분자량 분포가 좁으며, 공단량체의 조성 분포가 균일한 고분자가 얻어지며， 촉매의 리간드 구조 변형 및 중합 조건의 변경에 따라 고분자의 입체 규칙도, 공중합 특성， 분자량, 결정화도 등을 변화시킬 수 있는 특성을 가지고 있다.  Meanwhile, the metallocene catalyst is composed of a combination of a main catalyst composed mainly of transition metal compounds and a cocatalyst composed of organometallic compounds composed mainly of aluminum. Such a catalyst is a homogeneous complex catalyst and is a single site catalyst.

미국 특허 제 5,914,289호에는 각각의 담체에 담지된 메탈로센 촉매를 이용하여 고분자의 분자량 및 분자량 분포를 제어하는 방법이 기재되어 있으나, 담지촉매 제조시 사용된 용매의 양 및 제조시간이 많이 소요되고， 사용되는 메탈로센 촉매를 담체에 각각 담지시켜야 하는 번거로움이 따랐다. 대한민국 특허 출원 제 2003-12308호에는 담체에 이중핵 메탈로센 촉매와 단일핵 메탈로센 촉매를 활성화제와 함께 담지하여 반웅기 내 촉매의 조합을 변화시키며 중합함으로써 분자량 분포를 제어하는 방안을 개시하고 있다. 그러나， 이러한 방법은 각각의 촉매의 특성을 동시에 구현하기에 한계가 있으며 , 또한 완성된 촉매의 담체 성분에서 메탈로센 촉매 부분이 유리되어 반웅기에 파울링 (fouling)을 유발하는 단점이 있다. 따라서, 상기한 단점들을 해결하기 위해서 간편하게 활성이 우수한 흔성 담지 메탈로센 촉매를 제조하여 원하는 물성의 을레핀계 중합체를 제조하는 방법에 대한 요구가 계속되고 있다. U.S. Patent No. 5,914,289 describes a method for controlling the molecular weight and molecular weight distribution of a polymer using a metallocene catalyst supported on each carrier, but the amount of solvent used and the time required for preparing the supported catalyst are high. There was a hassle of supporting the metallocene catalyst to be used on the carrier, respectively. Korean Patent Application No. 2003-12308 discloses a binuclear metallocene in a carrier A method of controlling the molecular weight distribution by supporting a catalyst and a mononuclear metallocene catalyst together with an activator to change and polymerize the combination of catalysts in a reaction vessel is disclosed. However, this method has a limitation in realizing the characteristics of each catalyst at the same time, and also has a disadvantage in that the metallocene catalyst portion is liberated in the carrier component of the finished catalyst, causing fouling. Therefore, in order to solve the above disadvantages, there is a continuous need for a method for preparing a common supported metallocene catalyst having excellent activity to prepare a lelpene polymer having a desired physical property.
한편, 선형 저밀도 폴리에틸렌은 중합촉매를 사용하여 저압에서 에틸렌과 알파 을레핀을 공중합하여 제조되어, 분자량 분포가 좁고 일정한 길이의 단쇄분지를 가지며， 장쇄분지가 없는 수지이다. 선형 저밀도 폴리에틸렌 필름은 일반 폴리에틸렌의 특성과 더불어 파단강도와 신율이 높고, 인열강도, 낙추층격강도 등이 우수하여 기존의 저밀도 폴리에틸렌이나 고밀도 폴리에틸렌의 적용이 어려운 스트레치 필름， 오버랩 필름 등에의 사용이 증가하고 있다.  On the other hand, linear low density polyethylene is prepared by copolymerizing ethylene and alpha olefins at low pressure using a polymerization catalyst, and has a narrow molecular weight distribution, a short chain branch of a constant length, and a long chain branch. Linear low density polyethylene film has the characteristics of general polyethylene, and has high breaking strength and elongation, and excellent tear strength and falling layer stratification strength. Therefore, the use of stretch film and overlap film, which is difficult to apply to existing low density polyethylene or high density polyethylene, has increased. Doing.
그런데, 1-부텐 또는 1-핵센을 공단량체로 사용하는 선형 저밀도 폴리에틸렌은 대부분 단일 기상반응기 또는 단일 루프 슬러리 반응기에서 제조되며, 1-옥텐 공단량체를 사용하는 공정 대비 생산성은 높으나， 이러한 제품 역시 사용 촉매기술 및 공정기술의 한계로 물성이 1-옥텐 공단량체 사용시보다 크게 열세하고， 분자량 분포가 좁아 가공성이 불량한 문제가 있다. 이러한 문제의 개선을 위해 많은 노력이 진행되고 있으며,  By the way, linear low density polyethylene using 1-butene or 1-nuxene as comonomer is mostly produced in a single gas phase reactor or a single loop slurry reactor, and the productivity is high compared to a process using 1-octene comonomer, but these products are also used. Due to the limitations of catalyst technology and process technology, physical properties are inferior to those of using 1-octene comonomers, and molecular weight distribution is narrow, resulting in poor processability. Many efforts are being made to improve these issues.
미국 특허 제 4,935,474호에는 2종 또는 그 이상의 메탈로센 화합물이 사용되어 넓은 분자량 분포를 갖는 폴리에틸렌 제조법에 대해 보고되어 있다. 미국 특허 제 6,828,394호에는 공단량체 결합성이 좋은 것과 그렇지 않은 것을 흔합사용해 가공성이 우수하고 특히 필름용에 적합한 폴리에틸렌 제조방법에 대해 보고되어 있다. 또한, 미국 특허 제 6,841,631호, 미국 특허 게 6,894,128호에는 적어도 2종의 메탈 컴파운드가 사용된 메탈로센계 촉매로 이정 또는 다정 분자량분포를 갖는 폴리에틸렌을 제조하여， 필름, 블로우몰딩, 파이프 등의 용도에 적용이 가능하다고 보고되어 있다. 하지만 이러한 제품들은 가공성은 개선되었으나 단위 입자 내의 분자량별 분산상태가 균일하지 못해 비교적 양호한 압출조건에서도 압출외관이 거칠고 물성이 안정적이지 못한 문제가 있다. US Pat. No. 4,935,474 reports on the preparation of polyethylene having a wide molecular weight distribution using two or more metallocene compounds. U. S. Patent No. 6,828, 394 reports a method for producing polyethylene that has a good comonomer binding property and a good combination thereof, which has good processability and is particularly suitable for films. In addition, US Pat. No. 6,841,631 and US Pat. No. 6,894,128 prepare polyethylene having bimodal or polycrystalline molecular weight distribution with a metallocene catalyst using at least two metal compounds, for use in films, blow molding, pipes, and the like. It is reported to be applicable. However, these products have improved processability, but the molecular weight in the unit particles Since the dispersion state is not uniform, the extrusion appearance is rough and the physical properties are not stable even under relatively good extrusion conditions.
이러한 배경에서 물성과 가공성 간의 균형이 이루어진 보다 우수한 제품의 제조가 끊임없이 요구되고 있으며 이에 대한 개선이 더욱 필요한 상태이다.  Against this background, there is a constant demand for manufacturing a better product having a balance between physical properties and processability, and further improvement is required.

본 발명에 따른 을레핀계 중합체는 분자량 분포 (Mw/Mn)가 5 내지 30이고, 190°C에서 ASTM1238에 의하여 측정한 . 용융 유동율비 (MFR21.6/MFR2 16) 값이 35 내지 200이며, 주파수 (frequency, o [rad/s])에 따른 복소점도 (complex visicosity, *[Pa.s]) 그래프에서 기울기가 -0.8 내지 -0.2이고， CI(Q)-monomer Incorporation) Index 가 0.5 내지 5인 것을 특징으로 한다. Eulre pingye polymer according to the present invention is a molecular weight distribution (Mw / Mn) 5 to 30, measured by the ASTM1238 at 190 ° C. The melt flow rate ratio (MFR 21 .6 / MFR 2 16 ) has a value between 35 and 200, and the slope on the graph of complex visicosity (* [Pa.s]) according to frequency (o, [rad / s]) -0.8 to -0.2, CI (Q) -monomer Incorporation) Index is characterized in that 0.5 to 5.
본 발명의 올레핀계 중합체는 약 5 내지 약 30, 바람직하게는 약 6 내지 약 20 의 넓은 분자량 분포 (Mw/Mn, PDI)를 보여 우수한 가공성을 나타낼 수 있다.  The olefinic polymer of the present invention exhibits a broad molecular weight distribution (Mw / Mn, PDI) of about 5 to about 30, preferably about 6 to about 20, and can exhibit excellent processability.
본 발명의 일 실시예에 따르면， 상기 올레핀계 중합체의 중량 평균 분자량 (Mw)은 약 100,000 내지 약 300,000 g/mol, 바람직하게는 약 100,000 내지 약 250,000 g/mol 일 수 있으나， 이에만 한정되는 것은 아니다.  According to an embodiment of the present invention, the weight average molecular weight (Mw) of the olefin polymer may be about 100,000 to about 300,000 g / mol, preferably about 100,000 to about 250,000 g / mol, but is not limited thereto. no.
상기 본 발명의 을레핀계 중합체는 고분자량 및 넓은 분자량 분포를 가지며 물성 및 가공성이 우수한 효과가 있다.  The leulevine-based polymer of the present invention has a high molecular weight and a wide molecular weight distribution and has excellent physical properties and processability.
즉, 본 발명의 올레핀계 공중합체는， 알려진 올레핀계 공중합체에 비해 넓은 분자량 분포와 용융 유동률비 (MFRR)를 가져 유동성이 현저히 향상되어 보다 우수한 가공성을 나타낼 수 있다.  That is, the olefin copolymer of the present invention has a wider molecular weight distribution and a melt flow rate ratio (MFRR) than the known olefin copolymer, and thus the fluidity is remarkably improved, and thus, excellent workability can be exhibited.
본 발명의 을레핀계 공증합체는, 용융 유동율비 (MFRR, MFR21.6/MFR2.16) 가 약 35 내지 약 200, 바람직하게는 약 80 내지 약 150인 범위를 갖는다. 상기와 같은 범위의 용융 유동율비를 가짐으로써 각 하중에서의 흐름성이 적절히 조절되어, 가공성 및 기계적 물성이 동시에 향상될 수 있다. Eulre pingye notary polymer of the invention has a melt flow rate ratio (MFRR, MFR 21.6 / MFR 2 . 16) is about 35 to about 200, preferably from about 80 to about 150 range. By having the melt flow rate ratio in the above range, the flowability at each load can be appropriately adjusted, thereby improving workability and mechanical properties at the same time.
본 발명의 일 실시예에 따르면， MFR2.16(ASTM D-1238에 의거하여 190 °C , 2.16kg하중에서 측정된 용융 유동 지수)는 약 0.1 내지 약 3 g/10min일 수 있고， 바람직하게는 약 0.1 내지 약 0.8 g/10min의 범위일 수 있다. 또한, 본 발명의 일 실시예에 따르면， MFR21.6(ASTM D-1238에 의거하여 190°C , 21.6kg 하중에서 측정된 용융 유동 지수)은 약 5 내지 약 100 g/lOmin일 수 있고, 바람직하게는 약 7 내지 약 60 g/lOmin의 범위일 수 있다. 이러한 MFR2 16, MFR21.6의 범위는 상기 을레핀계 중합체의 용도 또는 적용 분야를 고려하여 적절히 조절될 수 있다. According to one embodiment of the invention, MFR 2 . 16 (melt flow index measured at 190 ° C, 2.16 kg load according to ASTM D-1238) may range from about 0.1 to about 3 g / 10 min, preferably in the range of about 0.1 to about 0.8 g / 10 min. Can be. Further, according to one embodiment of the present invention, MFR 21 . 6 (melt flow index measured at 190 ° C., 21.6 kg load according to ASTM D-1238) can range from about 5 to about 100 g / lOmin, preferably in the range from about 7 to about 60 g / lOmin. Can be. Such MFR 2 16 , MFR 21 . The range of 6 refers to the use or application of the olefinic polymer Can be adjusted appropriately.
또한, 본 발명의 올레핀계 중합체는 주파수 (frequency, ω [rad/s])에 따른 복소점도 (complex visicosity, ri *[Pa.s]) 그래프에서 기울기가 약 -0.8 내지 약 -0.2, 또는 약 -0.6 내지 -0.4인 범위를 갖는다. 주파수에 따른 복소점도 그래프는 유동성과 관련된 것으로, 낮은 주파수에서 높은 복소점도를 갖고 높은 주파수에서는 낮은 복소점도를 가질수록 유동성이 높은 것을 의미한다. 즉, 음의 기울기값을 가지며， 상기 기울기값의 절대값이 클수록 높은 유동성을 나타내는 것이라 할 수 있다. 본 발명의 을레핀계 중합체는 주파수에 따른 복소점도 그래프에서 기울기가 약 -0.8 내지 약 -으2인 범위로, 유사한 밀도 및 중량 평균 분자량을 갖는 종래의 을레핀계 중합체에 대비하여 현저히 높은 유동성을 보인다. 이에 딴라 높은 용융지수에도 불구하고 shear thinning 효과가 훨씬 뛰어나 우수한 유동성 및 가공성을 나타냄을 알 수 있다ᅳ  In addition, the olefinic polymer of the present invention has a slope of about -0.8 to about -0.2, or about in the complex viscosity (ri * [Pa.s]) graph according to frequency (ω [rad / s]). It ranges from -0.6 to -0.4. The graph of complex viscosity according to frequency is related to fluidity, which means that the fluidity is higher as it has a high complex viscosity at low frequency and a low complex viscosity at high frequency. That is, it has a negative inclination value, and as the absolute value of the inclination value increases, it can be said that it shows high fluidity. The leulevine-based polymer of the present invention exhibits significantly higher fluidity compared to the conventional leulevine-based polymer having a similar density and weight average molecular weight in a range of about -0.8 to about -2 in a complex viscosity graph with frequency. Therefore, despite the high melt index, the shear thinning effect is much better, indicating excellent fluidity and processability.
또, 본 발명의 올레핀계 중합체는 CI(Co-monomer Incorporation) Index 가 약 0.5 내지 5, 또는 약 1 내지 3, 또는 약 1 내지 1.5일 수 있다. 본 명세서에서 사용되는 CI 구조란， 알파 올레핀과 같은 공단량체의 함량이 고분자량 주쇄에 집중되어 있는 구조, 즉, 짧은 사슬 가지 (Short Chain Branch, SCB) 함량이 고분자량 쪽으로 갈수록 많아지는 새로운 구조를 의미한다. GPC-FTIR 장치를 이용하여 분자량, 분자량 분포 및 SCB 함량을 동시에 연속적으로 측정할 수 있으며, CI Index 는 분자량 (M)의 로그값 (log M)을 X축으로 하고, 상기 로그값에 대한 분자량 분포 (dwt/dlog M)를 y축으로 하여 분자량 분포 곡선을 그렸을 때, 전체 면적 대비 좌우 끝 20%를 제외한 가운데 60%의 좌측 및 우측 경계에서 SCB(Short Chain Branch) 함량 (탄소 1,000 개당의 탄소수 2 내지 7개의 결가지 (branch) 함량, 단위: 개 /1,000C)을 측정하여 하기 식 1로 그 값을 계산하여 구할 수 있다. 이 때, 고분자량쪽 SCB 함량과, 저분자량쪽 SCB 함량은 각각 가운데 60% 범위의 우측 및 좌측의 경계에서의 SCB 함량값을 의미한다. 이러한 . CI(Co-monomer Incorporation) Index 의 측정방법의 일 예는 도 4에 도시된 바와 같다.  In addition, the olefin polymer of the present invention may have a Co-monomer Incorporation (CI) Index of about 0.5 to 5, or about 1 to 3, or about 1 to 1.5. As used herein, the CI structure is a structure in which the content of comonomers such as alpha olefins is concentrated in the high molecular weight main chain, that is, a new structure in which short chain branch (SCB) content increases toward higher molecular weight. it means. Molecular weight, molecular weight distribution and SCB content can be measured simultaneously using the GPC-FTIR apparatus, CI Index is the logarithm of the molecular weight (M) (log M) X-axis, the molecular weight distribution for the log value When the molecular weight distribution curve is drawn with (dwt / dlog M) as the y-axis, SCB (Short Chain Branch) content (the number of carbons per 1,000 carbons) at the left and right boundaries of 60%, except for the left and right ends of 20% of the total area. To 7 branch content (unit: 1,000 / c) can be measured and calculated by the following formula (1). In this case, the high molecular weight side SCB content and the low molecular weight side SCB content mean SCB content values at the right and left boundaries of the middle 60% range, respectively. Such . An example of a method of measuring a Co-monomer Incorporation (CI) Index is shown in FIG. 4.
[식 1] (Ά ^ SC B ¾ ¾CS: ¾ ¾.) [Equation 1] (Ά ^ SC B ¾ ¾CS : ¾ ¾.)
CI Index = (i*¥¾ ¾¥scF¥f" CI Index = (i * ¥ ¾ ¾ ¥ scF ¥ f "
이때, CI Index 가 0 이하인 경우 CI 구조의 고분자가 아니고, 0 보다 큰 경우 CI 구조의 고분자라고 볼 수 있는데， 그 값이 클수록 CI 특성이 우수한 것으로 평가할 수 있다.  At this time, if the CI Index is 0 or less, it is not a polymer of CI structure, but if it is larger than 0, it can be regarded as a polymer of CI structure.

In general, the presence of LCB in an olefin polymer can be determined by whether it has an inflection point in the van Gurp-Palmen graph measured by rheometer equipment or whether it tends to diverge toward lower complex modulus. The x-axis of the van Gurp-Palmen graph is the absolute value of the complex modulus, and the y-axis is the phase angle.

It is characterized by having an inflection point at. The characteristic of the graph is represented by the LCB of the olefin-based polymer. The olephine-based polymer including the LCB has excellent swell, bubble stability, melt fracture, sagging time, and can be applied to various applications. It is possible to provide a pipe having physical properties.

Further, the mass ratio of the first metallocene compound represented by the formula (1) to the second metallocene compound represented by the formulas (3) to 5 is 10: 1 to 1:10, preferably 5: 1 to 1: 5 days. have. When the cocatalyst and the metallocene compound are included in the mass ratio, the active and polymer microstructures can be optimized.
본 발명에 따른 흔성 담지 메탈로센 촉매에 있어서, 상기 담체로는 표면에 하이드록시기를 함유하는 담체를 사용할 수 있으며, 바람직하게는 건조되어 표면에 수분이 제거된， 반응성이 큰 하이드록시기와 실록산기를 가지고 있는 담체를 사용할 수 있다.  In the common supported metallocene catalyst according to the present invention, a carrier containing a hydroxyl group on the surface may be used, and preferably a highly reactive hydroxyl group and a siloxane group which are dried to remove moisture on the surface. The carrier which has is used.
예컨대, 고온에서 건조된 실리카， 실리카 -알루미나, 및 실리카- 마그네시아 등이 사용될 수 있고, 이들은 통상적으로 Na20, K2C03, BaS04, 및 Mg(N03)2 등의 산화물, 탄산염， 황산염, 및 질산염 성분을 함유할 수 있다. 상기 담체의 건조 온도는 200 내지 800°C가 바람직하고, 300 내지 600°C가 더욱 바람직하며, 300 내지 400°C가 가장 바람직하다. 상기 담체의 건조 온도가 200 °C 미만인 경우 수분이 너무 많아서 표면의 수분과 조촉매가 반웅하게 되고， 800 °C를 초과하는 경우에는 담체 표면의 기공들이 합쳐지면서 표면적이 즐어들며， 또한 표면에 하이드톡시기가 많이 없어지고 실록산기만 남게 되어 조촉매와의 반웅자리가 감소하기 때문에 바람직하지 않다. For example, silica, silica-alumina, silica-magnesia, etc., dried at a high temperature can be used, and these are usually oxides, carbonates, such as Na 2 O, K 2 C0 3 , BaS0 4 , and Mg (N0 3 ) 2 , Sulfate, and nitrate components. The drying temperature of the carrier is preferably 200 to 800 ° C., more preferably 300 to 600 ° C., most preferably 300 to 400 ° C. When the drying temperature of the carrier is less than 200 ° C, the moisture is too much and the surface of the carrier reacts with it, and when it exceeds 800 ° C, the pores on the surface of the carrier are combined to enjoy the surface area, It is not preferable because a lot of oxy groups are lost and only siloxane groups remain to decrease the reaction space with the promoter.
상기 담체 표면의 하이드록시기 양은 0.1 내지 10 mmol/g이 바람직하며, 0.5 내지 5 mmol/g일 때 더욱 바람직하다. 상기 담체 표면에 있는 하이드록시기의 양은 담체의 제조방법 및 조건 또는 건조 조건, 예컨대 온도， 시간, 진공 또는 스프레이 건조 등에 의해 조절할 수 있다.  The amount of hydroxy groups on the surface of the carrier is preferably 0.1 to 10 mmol / g, more preferably 0.5 to 5 mmol / g. The amount of hydroxyl groups on the surface of the carrier can be controlled by the method and conditions for preparing the carrier or by drying conditions such as temperature, time, vacuum or spray drying.
상기 하이드록시기의 양이 0.1 mmol/g 미만이면 조촉매와의 반응자리가 적고， 10 mmol/g을 초과하면 담체 입자 표면에 존재하는 하이드록시기 이외에 수분에서 기인한 것일 가능성이 있기 때문에 바람직하지 않다. 본 발명에 따른 흔성 담지 메탈로센 촉매는, 예를 들어， 담체에 조촉매 화합물을 담지시키는 단계, 상기 담체에 상기 화학식 1로 표시되는 제 1 메탈로센 화합물을 담지시키는 단계， 및 상기 담체에 상기 화학식 3 내지 5로 표시되는 화합물 중 선택되는 제 2 메탈로센 화합물을 담지시키는 단계를 포함하여 제조될 수 있다. If the amount of the hydroxy group is less than 0.1 mmol / g, the reaction site with the promoter is small. If the amount of the hydroxy group is more than 10 mmol / g, it may be due to moisture other than the hydroxyl group present on the surface of the carrier particle. Not desirable The common supported metallocene catalyst according to the present invention may include, for example, supporting a cocatalyst compound on a carrier, supporting a first metallocene compound represented by Formula 1 on the carrier, and on the carrier. It may be prepared, including the step of supporting a second metallocene compound selected from the compounds represented by Formulas 3 to 5.

That is, the first metallocene compound is first supported on the carrier, and then the second metallocene compound is further supported to prepare a common supported metallocene catalyst, or the second metallocene compound is supported on the carrier. After supporting first, the common metallocene catalyst may be prepared by further supporting the first metallocene compound.
