The present invention relates to a method for producing polyolefin using a novel polymerization catalyst. Conventionally, in this type of technical field, the
A catalyst in which a transition metal compound such as a titanium compound is supported on magnesium halide is known from Publication No. 12105, and further Belgian Patent No. 742112
A catalyst made by co-pulverizing magnesium halide and titanium tetrachloride is known. However, in the production of polyolefins, it is desirable that the catalyst activity be as high as possible, and from this point of view, the polymerization activity of the method described in Japanese Patent Publication No. 39-12105 is still low, while the polymerization activity of the method of Belgian Patent No. 742112 is quite high. Although the cost has increased, improvements are still desired. Furthermore, in German Patent No. 2137872, the amount of magnesium halide used is substantially reduced by co-pulverizing magnesium halide, titanium tetrachloride, alumina, etc., but the activity per solid, which is a measure of productivity, No significant increase was observed, and a catalyst with even higher activity is desired. Further, in the production of polyolefin, it is desirable that the bulk specific gravity of the polymer produced be as high as possible from the viewpoint of productivity and slurry handling. From this point of view, the bulk specific gravity of the polymer produced by the method described in Japanese Patent Publication No. 39-12105 is low and the polymerization activity is not satisfactory.
Although the method of No. 742112 has a high polymerization activity, the bulk specific gravity of the resulting polymer is low, and improvements are desired. The present invention improves the above-mentioned drawbacks, provides a novel polymerization catalyst that can obtain polymers with high polymerization activity and high bulk specific gravity in high yield, and allows continuous polymerization to be carried out extremely easily, as well as an olefin polymer produced using the polymerization catalyst. This method provides a polymerization or copolymerization method, and because the polymerization activity is extremely high, the monomer partial pressure during polymerization is low, and the bulk specific gravity of the resulting polymer is high, so productivity can be improved.
In addition, the amount of catalyst residue in the resulting polymer after polymerization is extremely small, so the catalyst removal step can be omitted in the polyolefin manufacturing process, simplifying the polymer processing process and making polyolefins extremely economical overall. be able to. In the method of the present invention, since the bulk specific gravity of the obtained polymer is large, the amount of polymer produced per unit polymerization reactor is large. Furthermore, the advantages of the present invention are that although the bulk specific gravity of the produced polymer is high in terms of particle size, there are few coarse particles and fine particles of 50Ό or less, so continuous polymerization reaction is facilitated, and polymer processing is possible. This facilitates the handling of polymer particles, such as centrifugation and powder transportation in the process. Another advantage of the present invention is that the polyolefin obtained using the catalyst of the present invention has a large bulk specific gravity as described above, and the hydrogen concentration is required to obtain a polymer with a desired melt index compared to conventional methods. Therefore, the total pressure during polymerization can be made relatively small, which has a large effect on economic efficiency and productivity. In addition, when olefin is polymerized using the catalyst of the present invention, there is little decrease in the olefin absorption rate over time, so another advantage is that polymerization can be carried out for a long time with a small amount of catalyst. Furthermore, the polymer obtained using the catalyst of the present invention has an extremely narrow molecular weight distribution and is characterized by extremely low by-products of low polymers, such as a small amount of hexane extraction. Therefore, it is possible to obtain a product of good quality, such as film grade, which has excellent blocking resistance. The catalyst of the present invention has many of these characteristics,
Moreover, the present invention provides a novel catalyst system that improves the drawbacks of the prior art described above, and it must be said that it is surprising that these points can be easily achieved by using the catalyst of the present invention. The present invention will be specifically explained below. That is,
The present invention provides a method for polymerizing or copolymerizing an olefin using a solid catalyst component and an organic aminium compound (hereinafter referred to as an organic metal compound) as a catalyst, in which the solid catalyst component has at least the following three components (1) with the general formula R 1 n (OR 2 ) o MgX 2-no (here R 1 , R 2
represents a hydrocarbon residue having 1 to 24 carbon atoms, and X represents a halogen atom. m and n are 0âŠmâŠ2, 0<nâŠ
2,0<m+nâŠ2), (2) General formula

Specific examples of these include propane, butane, pentane, hexane, heptane, octane, benzene, toluene, xylene, various aliphatic saturated hydrocarbons such as cyclohexane, aromatic hydrocarbons, alicyclic hydrocarbons, and ethanol and diethyl. Examples include alcohols, ethers, and esters such as ether, tetrahydrofuran, ethyl acetate, and ethyl benzoate. The equipment used for co-pulverization is not particularly limited, but ball mills, vibration mills, rod mills, impact mills, etc. are usually used, and those skilled in the art can easily determine conditions such as grinding temperature and grinding time depending on the grinding method. It is something that can be done. Generally, the grinding temperature is 0°C to 200°C, preferably 20°C to 100°C,
The grinding time is 0.5 to 50 hours, preferably 1 to 30 hours. Of course, these operations should be carried out in an inert gas atmosphere, and moisture should be avoided as much as possible. In the present invention, a method of reacting components (1) to (3) in a solution or a method of co-pulverizing a material obtained by reacting components (1) and (2) in a solution with component (3) is particularly preferred. In addition to the above components (1) to (3), the present invention also includes a component (4) selected from organic halogen compounds, halogenating agents, phosphoric acid esters, electron donors, and polycyclic aromatic compounds. It is also preferably employed to use one or more kinds of compounds.
The reaction method when using component (4) is not particularly limited, but methods include a method of reacting components (1) to (4) in a solution, and a method of reacting components (1), (2), and (4) in a solution. A method of co-pulverizing the substance obtained by the above method and component (3) is preferably used. The organic halogen compound used at this time is a compound in which a portion of a saturated or unsaturated aliphatic hydrocarbon, aromatic hydrocarbon, etc. is substituted with a halogen, and includes mono-substituted compounds, di-substituted compounds, tri-substituted compounds, and the like. Further, the halogen may be any of fluorine, chlorine, bromine and iodine. Specifically, these organic halogen compounds include methylene chloride, chloroform, carbon tetrachloride,
Bromochloromethane, dichlorodifluoromethane, 1-bromo-2-chloroethane, chloroethane, 1,2-dibromo-1,1-dichloroethane, 1,1-dichloroethane, 1,2-dichloroethane, 1,2-dichloro-1, 1,2,2-tetrafluoroethane, hexachloroethane, pentachloroethane, 1,1,2,2-tetrachloroethane, 1,1,2,2-tetrachloroethane,

Can be used 1000mol times. Olefin polymerization using the catalyst of the present invention can be carried out by slurry polymerization, solution polymerization, or gas phase polymerization, and it can be particularly preferably used for gas phase polymerization. The polymerization reaction is carried out in the same manner as an ordinary olefin polymerization reaction using a Ziegler type catalyst. That is, all reactions are carried out in the presence or absence of inert hydrocarbons, substantially deprived of oxygen, water, and the like. The polymerization conditions for olefin are as follows: temperature is 20 to 120°C, preferably 50 to 100°C, and pressure is normal pressure to 70 kg/cm 2 , preferably 2 to 60 kg/cm 2 . Although the molecular weight can be adjusted to some extent by changing polymerization conditions such as polymerization temperature and catalyst molar ratio, it is effectively carried out by adding hydrogen to the polymerization system. Of course, using the catalyst of the present invention, a two-stage or more multi-stage polymerization reaction with different polymerization conditions such as hydrogen concentration and polymerization temperature can be carried out without any problem. The method of the present invention is applicable to the polymerization of all olefins that can be polymerized with Ziegler's catalyst, and α-olefins having 2 to 12 carbon atoms are particularly preferred, such as ethylene, propylene, 1-butene, hexene-1,4-methyl Homopolymerization of α-olefins such as pentene-1 and octene-1, ethylene and propylene, ethylene and 1-butene, ethylene and hexene-1, ethylene and 4-methylpentene-1, ethylene and octene-1, propylene and 1
- It is suitably used for copolymerization of butene, copolymerization of ethylene and two or more other α-olefins, etc. Copolymerization with dienes is also preferably carried out for the purpose of modifying polyolefins. Examples of diene compounds used at this time include butadiene, 1,4-hexadiene, ethylidenenorbornene, dicyclopentadiene, and the like. Examples will be described below, but these are for illustrative purposes to carry out the present invention, and the present invention is not limited thereto. Example 1 (a) Production of solid catalyst component Ethanol was added to a 50 c.c. three-necked flask equipped with a stirrer.
200 ml, 20 g of ethoxymagnesium chloride (Mg/Cl molar ratio = 0.81) obtained by treating magnesium diethoxide with HCl, 10 g of triethyl phosphate, and 20 g of tetraethoxysilane were added, and the mixture was reacted for 3 hours under ethanol reflux. . After the reaction is complete, remove the supernatant and add 200 ml of hexane.
Washed 3 times with ml. Then, 200 ml of hexane and 5 ml of titanium tetrachloride were added and reacted for 2 hours under hexane reflux. After the reaction was completed, the supernatant liquid was removed and washed five times with hexane to obtain a solid catalyst component containing 21 mg of titanium per gram. (b) Polymerization A stainless steel autoclave was used as the gas phase polymerization apparatus, a loop was created with a blower, a flow controller, and a dry cyclone, and the temperature of the autoclave was adjusted by flowing hot water through the jacket. The above solid catalyst component [] was fed at a rate of 50 mg/hr and triethylaluminum was fed at a rate of 5 mmol/hr to an autoclave adjusted to 80°C, and the butene-1/ethylene ratio (molar ratio) in the gas phase of the autoclave was set to 0.27. Furthermore, each gas was supplied while adjusting the hydrogen to 15% of the total pressure, and the gases in the system were circulated using a blower to maintain the total pressure.
Polymerization was carried out while maintaining the pressure at 10 kg/cm 2 ·G.
The produced ethylene copolymer had a bulk specific gravity of 0.29, a melt index (MI) of 1.1, and a density of 0.9208. The catalyst activity was 238,000 g copolymer/g Ti. After 10 hours of continuous operation, the autoclave was opened and the interior was inspected, but the inner walls and stirrer were clean with no polymer attached at all.
