【배경기술】  Background Art
을레핀 중합 촉매계는 지글러 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 적.용되어 왔으나, 활성점이 여러 개 흔재하는 다활성점 촉매 (multi site catalyst)이기 때문어)， 중합체의 분자량 분포가 넓은 것이 특징이며， 공단량체의 조성 분포가 균일하지 않아 원하는 물성 확보에 한계가 있다는 문제점이 있다. Ellefin 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. Ziegler-Natta catalysts have been widely used in conventional commercial processes since they were invented in the 50s . Has been used, but the active site is a multi-site catalyst (multi-site catalyst) is common, characterized by a wide molecular weight distribution of the polymer, and because the composition of the comonomer is not uniform distribution, there is a limit in securing the desired physical properties There is a problem.
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.  On the other hand, the metallocene catalyst is composed of a combination of a main catalyst composed mainly of a transition metal compound and a cocatalyst composed of an organometallic compound composed mainly of aluminum, and such a catalyst is a single site catalyst as a homogeneous complex catalyst. The polymer has a narrow molecular weight distribution according to the characteristics of a single active site and a homogeneous composition of the comonomer, and the stereoregularity, copolymerization characteristics, molecular weight, It has the property to change the crystallinity.
미국 특허 제 5,032,562호에는 두 개의 상이한 전이금속 촉매를 한 개의 담지 촉매 상에 지지시켜 중합 촉매를 제조하는 방법이 기재되어 있다. 이는 고분자량을 생성하는 티타늄 (Ti) 계열의 지글러 -나타 촉매와 저분자량을 생성하는 지르코늄 (Zr) 계열의 메탈로센 촉매를 하나의 지지체에 담지시켜 이정 분산 (bimodal distribution) 고분자를 생성하는 방법으로써， 담지 과정이 복잡하고, 조촉매로 인해 중합체의 형상 (morphology)이 나빠지는 단점이 있다. 미국 특허 제 5,525,678호에는 메탈로센 화합물과 비메탈로센 화합물을 담체 위에 동시에 담지시켜 고분자량의 중합체와 저분자량의 중합체가 동시에 중합될 수 있는 을레핀 중합용 촉매계를 사용하는 방법을 기재하고 있다. 이는 메탈로센 화합물과 비메탈로센. 화합물들을 각각 따로 담지시켜야 하고, 담지 반웅을 위해 담체를 여러 가지 화합물로 전처리해야 하는 단점이 있다. U. S. Patent No. 5,032, 562 describes a process for preparing a polymerization catalyst by supporting two different transition metal catalysts on one supported catalyst. It is a method of producing a bimodal distribution polymer by supporting a titanium (Ti) -based Ziegler-Natta catalyst generating high molecular weight and a zirconium (Zr) -based metallocene catalyst generating low molecular weight on one support. As a result, the supporting process is complicated, and the morphology of the polymer is deteriorated due to the promoter. U.S. Patent No. 5,525,678 describes a method of using a catalyst system for olefine polymerization in which a high molecular weight polymer and a low molecular weight polymer can be simultaneously polymerized by simultaneously supporting a metallocene compound and a nonmetallocene compound on a carrier. . It is a metallocene compound and a nonmetallocene . There is a disadvantage in that the compounds must be supported separately, and the carrier must be pretreated with various compounds for supporting reaction.
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.  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. The hassle of having to support the metallocene catalyst to be used on the carrier, respectively.
대한민국 특허 출원 제 2003-12308호에는 담체에 이중핵 메탈로센 촉매와 단일핵 메탈로센 촉매를 활성화제와 함께 담지하여 반응기 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.  Korean Patent Application No. 2003-12308 discloses a method of controlling the molecular weight distribution by supporting a double-nucleated metallocene catalyst and a mononuclear metallocene catalyst on a carrier together with an activator to polymerize by changing the combination of catalysts in the reactor. have. However, this method is limited 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.
따라서， 상기한 단점들을 해결하기 위해서 간편하게 활성이 우수한 흔성 담지 메탈로센 촉매를 제조하여 원하는 물성의 을레핀계 중합체를 제조하는 방법에 대한 요구가 계속되고 있다.  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 and preparing a olefinic polymer of desired physical properties.

본 발명에 따른 흔성 담지 메탈로센 촉매의 제조방법에 있어서, 상기 담체로는 표면에 하이드록시기를 함유하는 담체를 사용할 수 있으며, 바람직하게는 건조되어 표면에 수분이 제거된, 반웅성이 큰 하이드록시기와 실록산기를 가지고 있는 담체를 사용할 수 있다.  In the method for preparing a common supported metallocene catalyst according to the present invention, a carrier containing a hydroxyl group on the surface may be used, and preferably, a semi-astringent hydride is dried to remove moisture from the surface. The carrier which has a hydroxy group and a siloxane group can be 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. For example, silica, silica-alumina, silica-magnesia, etc., dried at a high temperature may be used, which are typically oxides, carbonates, such as Na 2 O, K 2 C0 3 , BaS0 4 , and Mg (N0 3 ) 2 , Sulfate, and nitrate components.
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， 80CTC를 초과하는 경우에는 담체 표면의 기공들이 합쳐지면서 표면적이 줄어들며, 또한 표면에 하이드록시기가 많이 없어지고 실록산기만 남게 되어 조촉매와의 반웅자리가 감소하기 때문에 바람직하지 않다. 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, there is too much moisture to react with the surface moisture and the promoter, and when it exceeds 80 CTC, the surface area decreases as the pores on the surface of the carrier are combined, and more hydroxyl groups are present on the surface. Disappear and only siloxane remains, and with the promoter It is not desirable because the reaction sign is reduced.
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 은도， 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 silver, time, vacuum or spray drying.
상기 하이드록시기의 양이 0.1 ' mmol/g 미만이면 조촉매와의 반웅자리가 적고, 10 mmol/g을 초과하면 담체 입자 표면에 존재하는 하이드록시기 이외에 수분에서 기인한 것일 가능성이 있기 때문에 바람직하지 않다.  If the amount of the hydroxy group is less than 0.1 'mmol / g, the reaction space with the promoter is small, and 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.
