In some cases, the absence of anhydrous surfactant results in the formation of fine catalyst-supported particles, while overuse creates a straw-shaped material sometimes referred to as a needle.

  The solid titanium catalyst component can be formed by contacting the magnesium compound, titanium compound, and internal electron donor by known methods used to prepare highly active titanium catalyst components.

Some examples of methods for producing solid titanium catalyst components are briefly described below.
(1) Optionally, a magnesium-based catalyst support having an internal electron donor is reacted with a titanium compound in a liquid phase.
(2) A magnesium-based catalyst support and a titanium compound are reacted in the presence of an internal electron donor to precipitate a solid titanium complex.
(3) The reaction product obtained in (2) is further reacted with a titanium compound.
(4) The reaction product obtained in (1) or (2) is further reacted with an internal electron donor and a titanium compound.
(5) The reaction product obtained in (1) to (4) is treated with a halogen, a halogen compound, or an aromatic hydrocarbon.
(6) The magnesium-based catalyst support is reacted with any internal electron donor, titanium compound, and / or halogen-containing hydrocarbon.
(7) The magnesium-based catalyst support is brought into contact with the titanium compound in the liquid phase, filtered and washed. The reaction product is further reacted with an internal electron donor and a titanium compound and then activated with additional titanium compound in an organic medium.

  In an embodiment for producing a solid titanium catalyst component according to Examples (2), (3), (4), and (5), the magnesium-based solution is mixed with a titanium compound such as liquid titanium tetrahalide, and optionally In the presence of an auxiliary precipitant, a solid precipitate is formed. Prior to, during, or after precipitation of the solid, a polycarboxylic acid ester can be added and loaded onto the solid.

  The solid precipitation process can be carried out by at least one of three methods. One method mixes the magnesium-based solution and a titanium compound such as liquid titanium tetrahalide at a temperature in the range of about −40 ° C. to about 0 ° C., while the temperature is between about 60 ° C. and about 100 ° C. With a slow rise to a range of about 30 degrees Celsius to about 120 degrees Celsius. The second method involves adding a titanium compound dropwise to a magnesium-based solution at a low temperature or room temperature, and immediately depositing a solid. The third method involves dripping the first titanium compound into the magnesium-based solution and mixing the magnesium support and the second titanium compound. In these methods, an internal electron donor can desirably be present in the reaction system. The internal electron donor can be added either after obtaining the magnesium-based solution or after forming the magnesium-based catalyst support. Alternatively, an auxiliary precipitant can be added to form a magnesium-based catalyst support.

The catalyst precursor can be formed by the following method. A solution containing magnesium and titanium in a solvent such as toluene is found after the addition of a halogenating agent such as TiCl ₄ at a relatively low temperature from −25 ° C. to about 0 ° C. An oil phase is then formed, which can be dispersed in a hydrocarbon phase that is stable up to about 40 degrees Celsius. The resulting magnesium material becomes semi-solid at this point, where the particle morphology is determined. The semi-solid converts to a solid at about 40 degrees Celsius to about 80 degrees Celsius.

  The precipitation process can be carried out slowly in order to easily obtain uniform solid particles. If a second method of dropping titanium halide at low or room temperature is applied, the process can be performed over a period of about 1 hour to about 6 hours. When the first method of increasing the temperature by slow means is applied, the rate of temperature increase can range from about 4 degrees Celsius to about 100 degrees Celsius per hour.

  First, a solid precipitate is separated from the mixture. The solid precipitate obtained in this way can give a variety of complexes and by-products and in some cases may require further processing. In one embodiment, the solid precipitate is treated with a titanium compound and substantially removes by-products from the solid precipitate.

  The solid precipitate can be washed with an inert diluent and then treated with a titanium compound or a mixture of a titanium compound and an inert diluent. The titanium compound used in this treatment can be the same or different from the titanium compound used to form the solid precipitate. The amount of titanium compound used is about 1 to about 20 moles, for example about 2 to about 15 moles per mole of magnesium compound in the support. Processing temperatures range from about 50 degrees Celsius to about 150 degrees Celsius, such as from about 60 degrees Celsius to about 100 degrees Celsius. When treating a solid precipitate using a mixture of titanium tetrahalide and an inert diluent, the volume percent of titanium tetrahalide in the treatment solution is from about 10% to about 100%, the rest An inert diluent.

  The treated solid can be further washed with an inert diluent to remove ineffective titanium compounds and other by-products. The inert diluent used herein can be hexane, heptane, octane, 1,2-dichloroethane, benzene, toluene, ethylbenzene, xylene, and other hydrocarbons.

  By treating the solid precipitate with a titanium compound and optionally an inert diluent, by-products in the solid precipitate can be removed from the solid precipitate. In one embodiment, the solid precipitate is treated with the titanium compound and optionally an inert diluent at least about 2 and up to 5 times.

  By treating the solid precipitate with an inert diluent, the free titanium compound in the solid precipitate can be removed from the solid precipitate. As a result, the resulting solid precipitate is substantially free of free titanium compounds. In one embodiment, the solid precipitate is repeatedly treated with an inert diluent until the filtrate contains about 100 ppm or less of titanium. In another embodiment, the solid precipitate is repeatedly treated with an inert diluent until the filtrate contains about 50 ppm or less of titanium. In yet another embodiment, the solid precipitate is repeatedly treated with an inert diluent until the filtrate contains about 10 ppm or less of titanium. In one embodiment, the solid precipitate is treated with an inert diluent about 3 to 7 times.

  In one embodiment, particularly the embodiment after Example (2) above, the solid catalyst component has the following chemical composition: About 0.5 to about 6.0 weight percent titanium, about 10 to about 25 weight percent magnesium, about 40 to about 70 weight percent halogen, about 1 to about 25 weight percent internal electron donor, and optionally About 0 to about 15% by weight of an inert diluent.

  The polymerization of olefins according to the invention is carried out in the presence of the catalyst system described above. Generally speaking, the olefin is contacted with the catalyst system described above under suitable conditions to form the desired polymer product. In one embodiment, the pre-polymerization described above is performed before the main polymerization. In another embodiment, the polymerization is performed without prepolymerization. In yet another embodiment, the formation of the copolymer is performed using at least two polymerization regions.

  In the prepolymerization, the solid titanium catalyst component is usually employed in combination with at least a part of the organoaluminum compound. This can be done in the presence of some or all of the organosilicon compound (external electron donor). The concentration of the catalyst system used in the prepolymerization can be much higher than that of the main polymerization reaction system.

  In the prepolymerization, the concentration of the solid titanium catalyst component in the prepolymerization is usually about 0.01 to about 200 mmol, preferably about 0.05, calculated as per liter of the inert hydrocarbon medium described below. In the range of ~ 100 mmol. In one embodiment, the prepolymerization is performed by adding the olefin and the catalyst system components described above to an inert hydrocarbon medium and reacting with the olefin under mild conditions.

  Specific examples of inert hydrocarbon media include aliphatic hydrocarbons such as propane, butane, pentane, hexane, heptane, octane, decane, dodecane, and kerosene; alicyclics such as cyclopentane, cyclohexane, and methylcyclopentane Formula hydrocarbons; aromatic hydrocarbons such as benzene, toluene, and xylene; halogenated hydrocarbons such as ethylene chloride and chlorobenzene; and mixtures thereof. In the present invention, liquid olefins can be used as a substitute for partial or total inert hydrocarbon media.

  The olefin used in the prepolymerization can be the same as or different from the olefin to be used in the main polymerization.

  The reaction temperature for the prepolymerization is sufficient for the resulting prepolymer that does not substantially dissolve in the inert hydrocarbon medium. In one embodiment, the temperature ranges from about -20 degrees Celsius to about 100 degrees Celsius. In another embodiment, the temperature is from about -10 degrees Celsius to about 80 degrees Celsius. In yet another embodiment, the temperature is between about 0 degrees Celsius and about 40 degrees Celsius.

  Optionally, a molecular weight control agent such as hydrogen may be used for the prepolymerization. The molecular weight control agent is used in such an amount that the polymer obtained by pre-polymerization has an intrinsic viscosity and is at least about 0.2 dl / g and preferably about 0.5 to 10 dl / g at 135 degrees Celsius. Measured in decalin.

  In one embodiment, the prepolymerization is desirably carried out such that from about 0.1 g to about 1,000 g of polymer is formed per gram of titanium catalyst component of the catalyst system. In another embodiment, the prepolymerization is desirably carried out such that from about 0.3 g to about 500 polymers are formed per gram of titanium catalyst component. If the amount of polymer formed by the prepolymerization is too high, the efficiency of producing the olefin polymer in the main polymerization can sometimes be reduced, and if the resulting olefin polymer is formed into a film or another article, Spots tend to occur on the molded product. The prepolymerization can be performed batchwise or continuously.

  After prepolymerization as described above, or after no prepolymerization, the main polymerization of the olefin is formed from a solid titanium catalyst component, an organoaluminum compound, and an organosilicon compound (external electron donor). It is carried out in the presence of the above-mentioned olefin polymerization catalyst system.

  Examples of olefins that can be used in the main polymerization are ethylene, polypropylene, 1-butene, 4-methyl-1-pentene, 1-pentene, 1-octene, 1-hexene, 3-methyl-1-pentene, 3- It is an α-olefin having 2 to 20 carbon atoms such as methyl-1-butene, 1-decene, 1-tetradecene, 1-eicocene, and vinylcyclohexane.

When this mixed olefin is used, the proportion of propylene or 1-butene as the main component is usually at least about 50 mol%, preferably at least about 70 mol%.

  By performing the prepolymerization, the catalyst system in the main polymerization can be adjusted in the degree of activity. This adjustment tends to obtain a powdery polymer with a high bulk density. Furthermore, when the prepolymerization is performed, the fluid shape of the resulting polymer is spherical, and in the case of slurry polymerization, the slurry obtains superior properties, while in the case of gas phase polymerization, the polymer bed Get outstanding properties. Furthermore, in these embodiments, polymers having a high stereoregularity index with high catalytic efficiency can be produced by polymerizing α-olefins having at least about 3 carbon atoms. Thus, when producing propylene copolymers, the resulting copolymer powder or copolymer is easy to handle.

  In the homopolymerization or copolymerization of these olefins, polyunsaturated compounds such as conjugated or non-conjugated dienes can be used as comonomers. Examples of comonomers include styrene, butadiene, acrylonitrile, acrylamide, α-methylstyrene, chlorostyrene, vinyl toluene, divinyl benzene, diallyl phthalate, alkyl methacrylate, and alkyl acrylate. In one embodiment, these comonomers include thermoplastic monomers and elastomeric monomers.

  When organoaluminum compounds and organosilicon compounds are partially used in the prepolymerization, the catalyst system subjected to the prepolymerization is used with the remaining catalyst system components. The catalyst system subjected to the prepolymerization may contain a prepolymerized product.

The use of hydrogen during polymerization contributes to promoting and controlling the molecular weight of the resulting polymer, and the resulting polymer can have a high melt flow rate. In this case, the stereoregularity index of the resulting polymer and the activity of the catalyst system increase according to the method of the present invention. In one embodiment, the polymerization temperature ranges from about 20 degrees Celsius to about 200 degrees Celsius.

With impact copolymers, excellent fluidity, low temperature resistance, and the desired balance of hardness and elasticity can be obtained.

This catalyst system may be subjected to the above-mentioned prepolymerization. In another embodiment, propylene and ethylene rubber are formed in two reactors connected in series to form an impact copolymer.

In another embodiment, a poly-α-olefin having xylene solubility (XS) of about 1.5% to about 6% is produced according to the present invention. XS refers to the percentage of solid polymer that is soluble in xylene. A low XS% value generally corresponds to a high isotactic polymer (ie, high crystallinity), and a high XS% value generally corresponds to a low isotactic polymer.

  An example of a system for polymerized olefin will now be described. Referring to FIG. 1, a high level schematic diagram of a system 10 for polymerized olefins is shown. Inlet 12 is used to introduce catalyst system components, olefins, optional comonomer, hydrogen gas, fluid medium, pH adjuster, surfactant, and optional other additives to reactor 14. Although only one inlet is shown, multiple inlets may be employed. Reactor 14 is any suitable vehicle capable of polymerizing olefins. Examples of reactor 14 include a single reactor, a series of two or more reactors, a slurry reactor, a fixed bed reactor, a gas phase reactor, a fluidized bed gas reactor, a loop reactor, a multi-zone circulation reaction. Etc. are included. When the polymerization is complete or the polyolefin is produced, the polymer product is removed from the reactor 14 via the outlet 16 which is directed to the collector 18. The collector 18 may include downstream processes such as heating, extrusion, molding and the like.

  Referring to FIG. 2, there is a schematic diagram of a multi-zone circulating reactor 20 that can be employed as the reactor 14 of FIG. 1 for producing polyolefins and the reactor 44 of FIG. The multi-zone circulating reactor 20 substitutes a series of separate reactors in a single reactor loop that allows different gas phase polymerization conditions on the two sides by using a liquid barrier. In the multi-zone circulating reactor 20, enrichment of the olefin monomer and optionally one or more co-monomers is started in the first zone. The second region is rich in hydrogen gas and the high velocity gas flow breaks apart the growing resin particles. These two regions produce resins of different molecular weight and / or monomer composition. The polymer granules grow as they circulate through the loop, forming alternating layers of each polymer portion in an onion shape. Each polymer particle constitutes an intimate bond between both polymer parts.

  In operation, the polymer particles pass through the flowing gas in the ascending side 24 of the loop and descend through the liquid monomer on the descending side 26. The same or different monomers (and optionally one or more comonomers) can be added to the legs of the two reactors. The reactor uses the catalyst system described above.

  In the liquid / gas separation region 30, hydrogen gas is removed and cooled and recirculated. The polymer particles are then packed on top of the descending side 26 and they descend. In this section, the monomer is introduced as a liquid. The conditions at the top of the descending side 26 can vary with different combinations and / or proportions of monomers in successive passages.

  Referring to FIG. 3, a high level schematic diagram of another system 40 for polymerized olefins is shown. This system is optimal for producing impact copolymers. A reactor 44, such as a single reactor, a series of reactors, or a multi-zone circulating reactor, is combined with a downstream gas phase or fluidized bed reactor 48 containing the catalyst system described above, and is a conventional catalyst. It is intended to produce an impact copolymer that has the desired impact / stiffness balance or is softer than an impact copolymer produced using the system. Inlet 42 is used to introduce catalyst system components, olefins, optional comonomer, hydrogen gas, fluid medium, pH adjuster, surfactant, and optional other additives to reactor 44. Although only one inlet is shown, multiple inlets may be employed. Through the transport means 46, the polyolefin produced in the first reactor 44 is sent to the second reactor 48. Feed means 50 is used to introduce catalyst system components, olefins, optional comonomer, fluid medium, and optional other additives. The second reactor 48 may or may not contain catalyst system components. Also, although only one inlet is shown, multiple inlets may be employed. When the second polymerization is complete or the impact copolymer is produced, the polymer product is removed from the second reactor 48 via an outlet 52 that leads to a collector 54. The collector 54 may include downstream processes such as heating, extrusion, molding and the like. At least one of the first reactor 44 and the second reactor 48 contains a catalyst system according to the present invention.

  When producing impact copolymers, polypropylene can be formed in a first reactor, while ethylene propylene rubber can be formed in a second reactor. In this polymerization, the ethylene propylene rubber in the second reactor is formed with a polypropylene matrix (and particularly in the pores) formed in the first reactor. Therefore, an intimate mixture of impact copolymers is formed, where the polymer product occurs as a single polymer product. Such an intimate mixture cannot be produced by simply mixing the polypropylene product with the ethylene propylene rubber product.

  Control the system and reactor, optionally using feedback based on continuous or intermittent tests, using a processor optionally equipped with memory and controller, not shown in any drawing Can do. For example, the processor may use one or more units to monitor and / or control the polymerization process based on pre-set data regarding the reaction and / or based on test / measurement data generated during the reaction. The reactor, inlet, outlet, test / measurement system connected to the reactor, and the like. As directed by the processor, the controller can control valves, flow rates, amount of material entering the system, reaction conditions (temperature, reaction time, pH, etc.), and the like. The processor may contain or be coupled to a memory containing data relating to various aspects of the polymerization process and / or a system associated with the polymerization process.

The solid was resuspended in 38 ml toluene and 0.43 g 9- (n-butylcarbonyl) -9'-methoxymethylfluorene was added to the reactor (toluene addition). The mixture was stirred at 85 degrees Celsius and 200 rpm for 1 hour. After filtration and washing twice with 65 ml of toluene, the mixture was left in toluene overnight under N ₂ .

After the toluene was filtered off, 66.25 ml of 10% by volume TiCl ₄ in toluene was added, a then heated to 95 degrees Celsius and held with stirring at 400 rpm for 1 hour (first activity Added). The solid was filtered and then resuspended in 66.25 ml of TiCl ₄ in 10% by volume toluene. The mixture was held at 110 degrees Celsius for 30 minutes, after which the solid was filtered again. This action was repeated two more times. The final catalyst was washed 4 times with 65 ml of hexane and then removed from the reactor in hexane.

Propylene polymerization was carried out in a 3.4 liter reactor. The reactor was purged at 100 degrees Celsius for 1 hour under nitrogen. At room temperature, 1.5 ml of triethylaluminum in 25 wt% heptane was added to the reactor. Then, 1.0 ml of 0.0768M cyclohexylmethyldimethoxysilane solution and 1 ml of 1 wt% catalyst slurry were added to the reactor sequentially. The reactor was pressurized to 3.5 psig with H ₂ and then charged with 1500 ml of propylene. The reactor was heated to 70 degrees Celsius and then held for 1 hour. At the end of the hold, the reactor was emptied and the polymer was recovered.
