Description

TECHNICAL FOR MANUFACTURING POLYBUTENE-1 HOMOPOLYMER OR COPOLYMER}

The present invention relates to a method for producing a polybutene-1 homopolymer, and more particularly, to a method for producing a polybutene-1 homopolymer, in which slurry polymerization can be used in addition to solution polymerization by using propane as a reaction solvent.

In general, polybutene-1 is a semicrystalline polymer containing 1-butene as a monomer and is a high molecular weight polyolefin having general properties similar to those of polyethylene and polypropylene.

Stereoregular polybutene-1 has high warpage resistance and miscibility with other polymers, has unique properties such as rheological properties and crystal behavior, and shows similar melting point as polypropylene and low density polyethylene and high density polyethylene. . It also has excellent stability such as long-term durability even at high temperatures. In addition, the stereoregular polybutene-1 has an advantage that it can be easily applied using a processing machine such as extrusion, injection, or blow molding, which has been applied to conventional polyolefins.

The temperature range of the stereoregular polybutene-1 is about -20 ° C to 105 ° C, and is widely used for cold and hot water piping, for flexible wrapping paper opening, as a softening agent for a polypropylene film and fiber, or as a hot melt adhesive performance enhancing agent. .

As a method of preparing the polybutene-1, a method of preparing a hydrocarbon having 4 or more carbon atoms as a solvent and a method of preparing 1-butene itself as a solvent have been reported. A method of preparing 1-butene itself as a solvent is used.

Stereoregular polybutene-1 is generally obtained by polymerizing 1-butene in the presence of an organoaluminum compound such as diethylaluminum chloride and a main catalyst composed mainly of titanium trichloride. In this method, the stereospecificity has not been sufficiently high to remove non-stereoregular polybutene-1. In addition, there is a need for a process for removing catalyst residues that adversely affects polymer properties due to low activity.

Stereoregular polybutene-1 may also be obtained by polymerizing 1-butene in the presence of a catalyst system consisting of titanium supported on magnesium chloride and an internal electron donor. However, this method also suffers from the fact that the titanium component at the ppm (weight) level remains in the polymer because it cannot obtain catalytic activity at the level of the existing high activity polyethylene or polypropylene.

As a specific example of a conventional method for producing a stereoregular polybutene-1, Patent Document 1 uses a lower hydrocarbon such as normal butane, isobutane, normalpentane, isopentane and cyclopentane as a solvent, and Ziegler-Natta type. A method of preparing polybutene-1 having high stereoregularity in the form of particles by polymerization of a catalyst, an organoaluminum compound, an external electron donor (Lewis base) and 1-butene was polymerized at a temperature of 20 ° C to 45 ° C. In order to solve the problem of separating the solvent from the polybutene-1 thus prepared.

This polybutene-1 manufacturing method has the advantage of not having to remove the non-stereoregular polybutene-1 due to the very high stereoregularity of 98 or more and easy separation from the solvent. However, since catalyst activity is 2,360 g / g-cata · 4 h, that is, low activity of 590 g / g-cata · h, a catalyst residue removal process for reducing the physical properties of the polymer is required. The disadvantage is that it is difficult to apply.

On the other hand, as a specific example of a conventional method for producing polybutene-1, when looking at Patent Document 2, 1-butene itself is used as a solvent and a monomer, tributylaluminum (TIBA) and diisopropyl as an external electron donor Dimethoxy silane (DIPMS) was used and 1-butene was prepared via two stage polymerization in the presence of a magnesium chloride supported main catalyst.

They have high stereoregularity through the above-described preparation method, and have obtained satisfactory physical properties by preparing polybutene-1 having a catalyst residue of 50 ppm or less based on titanium and having a molecular weight distribution of 6 or more, and the catalytic activity is polybutene- It showed an activity of 14,000 g / g-cata.4h, that is, 3,500 g / g-cata.h, based on one homopolymer. However, the method of preparing polybutene-1 according to the above method is by solution polymerization or bulk polymerization, and the reaction after the reaction is a flash process, a pelletizing process or a crumb for treating a polymer in a solution state. There is a problem that is limited to the process.

In the first step to prepare a polybutene-1 homopolymer, a solvent is added to the reactor, and it is preferable to add a cocatalyst of an organometallic compound and an external electron donor to undergo pretreatment. At this time, the reactor is cleaned by repeatedly adding vacuum and inert gas to the reactor, and then 1-butene (1-Butene) is put into the reactor, and the pre-treatment is sufficiently performed while mixing the organometallic compound, which is a cocatalyst, and an external electron donor. The cocatalyst, the organometallic compound, is contacted with a main catalyst component such as Ziegler-Natta system in the second process to polymerize 1-butene (1-Butene).

Undesired catalyst poisons in the reactor, specifically, catalyst poisons such as water, oxygen, carbon monoxide, carbon dioxide, acetylene, etc., must be removed in advance, for this purpose, either by vacuum, by inert gas, or by vacuum substitution. Inert gas replacement is performed in parallel to remove the catalyst poison.

In the second process, a main catalyst component and an inert gas are added thereto, and the polymerization is performed by heating to a corresponding polymerization temperature while stirring. At this time, the molecular weight regulator can be added together. 1-Butene used as the reaction monomer may be added together with the initial solvent of the reaction, or may be continuously supplied after the addition of the catalyst.

The main catalyst component, which is a polymerization catalyst such as Ziegler-Natta type, is introduced into a reactor, a molecular weight regulator is added, and then pressure is applied with an inert gas, followed by stirring to raise the temperature to the polymerization temperature, followed by polymerization.

At this time, the polymerization reaction temperature is preferably 0 ℃ to 110 ℃, more preferably carried out at 0 ℃ to 90 ℃. In order to induce slurry polymerization, it is even more preferable to keep the reaction temperature as low as about 0 ° C to 45 ° C.

And the pressure used is carried out under the conditions of about 1 bar to 1000 bar, preferably 1 bar to 60 bar. The polymerization time is, for example, generally about 10 minutes to 20 hours, preferably about 30 minutes to 4 hours in the case of a batch reaction, and generally about 10 minutes in the case of a continuous (CSTR) reaction. It is preferred to have an average residence time of from about 20 hours, preferably about 30 minutes to 4 hours.

Hydrogen is used as the molecular weight regulator to control the polymer molecular weight. On the other hand, the polymer molecular weight may be adjusted by adjusting the reaction temperature.

This second process leads to slurry polymerization in addition to solution polymerization, in particular by using propane as a solvent in the reaction system. In this case, an appropriate solvent and an appropriate reaction temperature may be selected to induce slurry polymerization.

The present invention also provides a polybutene-1 homopolymer prepared according to the above process. The obtained polybutene-1 homopolymer shows the shape of a solid slurry or powder.

After the reaction was completed, the solid product was separated by filtration, heptane was added and washed four times, heptane was added again, titanium chloride was added and reacted at 98 ° C. for 2 hours. As a result, the solid catalyst component produced here was separated by filtration and heptane was added to thoroughly perform the washing operation until the free titanium compound was no longer detected to obtain a solid catalyst component suspended in heptane.

The obtained catalyst constituents were analyzed using ICP and found to be 2-3 wt% titanium and 16-19 wt% magnesium.

Thereafter, 85 g of 1-butene (1-Butene) was continuously added over 3 hours, followed by further polymerization for 3 hours. Reactor agitation speed was 500 rpm.

Thereafter, the reactor was depressurized to remove unreacted 1-butene monomer, and the obtained polymer was dried at 40 ° C. under vacuum for 24 hours.
