Abstract

PURPOSE:To obtain the titled useful slurry with a high specific surface area, by polymerizing acetylene in the presence of a specified amount of a catalyst consisting mainly of a transition metal compound and an organometallic compound and continuing forced agitation over substantially the entire period from the start to the end of the polymerization. CONSTITUTION:Acetylene is slurry-polymerized by using a catalyst consisting mainly of a transition metal compound (e.g., preferably, titanium compound) and an organometallic compound (e.g., preferably, trialkylaluminum). In this reaction, the concentration of the transition metal compound is selected to be at least 0.001mol% based on solvent, and the polymerization is carried out under the condition in which forced agitation of the system is continued substantially. The resulting slurry of whiskered star-like polyacetylene can be handled like a fluid. Although the individual particles in the slurry are separated from each other, they, when molded from a wet cake obtained by separation of solvent or the like, form a molding of a desired shape by entanglement of whiskers because they are a star-like product having a number of whiskers.

The polyacetylene obtained when acetylene is polymerized using a catalyst system mainly composed of transition metal compounds and organometallic compounds, that is, the Ziegler-Natsuta catalyst, has electrical conductivity that can be controlled over a wide range from semiconductor regions to conductor regions, and is lightweight. There are great expectations for its use in the future as electronic components, battery electrodes, solar cells, etc.

(JP-A-55-129404, JP-A-55-14571
0) In the method (a), a uniform and dense film-like product can be produced in a short time, but it is difficult to control the thickness and the surface area is small, making it unsuitable for applications such as electrodes.

In the method (b), since the acetylene polymer is obtained as an integral gel ring in the reactor, it is very difficult to remove it from the reactor and is therefore unsuitable for industrial production. In addition, catalyst removal and cleaning operations are performed using a gel-like substance, so
The work is quite difficult and requires a considerable amount of cleaning fluid, making it unsuitable for industrial production.

Furthermore, the specific surface area of the molded product obtained by pressing the gel-like material is larger than that of the film-like material (a), but is not sufficient.

The reason why the specific surface area must be large is that when a polyacetylene molded body is used as an electronic component, such as an electrode, in order to efficiently exchange ions, etc. with the electrolyte, the area of the interface between the electrode and the electrolyte must be small. This is because making it bigger is essential.

The inventors of the present invention have conducted intensive research to solve the above problems, and have found that acetylene is polymerized using a specific amount of a catalyst mainly composed of a transition metal compound and an organometallic compound, and forced stirring during polymerization. It has been discovered that a polyacetylene molded article obtained from a polyacetylene slurry obtained by conducting the polymerization under substantially continuous conditions from the start of polymerization to the end of polymerization has a large specific surface area and is extremely useful, and a method for obtaining the necessary polyacetylene slurry. This has led to the present invention.

The slurry of star-shaped polyacetylene with whiskers obtained by the present invention can be handled as a fluid, and is therefore extremely advantageous for industrial handling, unlike known gel-like materials whose entire system is agar-like. . In addition, although each particle in the slurry is independent, each particle has many whiskers τ, so when it is separated from the solvent etc. and molded into a polyacetylene molded body from a wet cake, the whiskers of each particle are separated. By intertwining the two, a molded article having a desired shape and having appropriate strength can be easily obtained. The molded product obtained has an extremely large specific surface area.

The forced stirring performed in the present invention may be any method as long as it can sufficiently mix the inside of the system.Generally, it is a method using a paddle type, scree type, or turbine type stirring blade. With weak stirring using a so-called magnetinox stirrer, which is carried out on a laboratory scale, it becomes difficult to stir as polyacetylene is formed, and eventually the entire system becomes agar-like, and it does not become a slurry, and this gel-like material is difficult to clean. However, even if a molded product is obtained, its specific surface area is small and its practical value is low. It is also necessary that stirring be continued substantially throughout the reaction time.

Note that the initial stirring described in JP-A-55-129404 is only useful for the purpose of ripening the catalyst with acetylene, and in this case, the entire polymerization system becomes a single agar-like structure, resulting in the whiskered star-like structure of the present invention. I'm not happy with the polyacetylene slurry.

~ of the star-like polyacetylene with whiskers obtained by the present invention
The slurry is clearly distinguishable from a film-like or integral gel-like mass, is highly fluid, and when observed under a microscope, the polymer maintains a star-like shape with many whiskers. If it is necessary to remove the catalyst from this polyacetylene slurry, it is sufficient to simply wash the resulting slurry with a solvent that dissolves the catalyst (e.g., the same solvent used in the polymerization). .. Its operation is extremely easy and it is industrially very advantageous.

It was flowed into the gas phase section of the container at a flow rate of CZ. After 5 minutes, the polymer solution began to turn a tinge of purple, and a whisker-like polymer began to form. After 15 minutes, the system became sluic IJ +-, and after 30 minutes, the acetele/gas was stopped, the gas phase was replaced with nitrogen, and the temperature was returned to room temperature. A portion of the sample was taken out, the polymerization solvent was removed by drying, and the yield of the entire multipolymerization system was calculated from the weight of the polyacetylene and found to be 14.9N.
