6号公報などである。Conventional Structures and Problems There has been active development in recent years of techniques for utilizing low-concentration oxygen, that is, so-called oxygen-enriched air having an oxygen content of 21 to 40 degrees. This oxygen-enriched air is expected to have a variety of uses, including energy saving in combustion systems, oxygen therapy in the medical field, sludge treatment, and oxidation processes in the chemical industry. Regarding the method for producing oxygen-enriched air, a membrane separation method using a so-called gas-permeable membrane is attracting attention because of its economic efficiency, safety, and ease of handling. In the separation and concentration of gases, the performance points required of the gas permeable membrane used are the permeability coefficient of the target gas and the high selectivity in separation from other gases. In particular, in the case of producing oxygen-enriched air for the purpose of energy saving in combustion systems, a large amount of air is required, and a membrane material with a higher permeability coefficient is required. Polydimethylsiloxane (so-called silicone rubber) is well known as a material with a higher permeability coefficient than before, and Po2 (oxygen permeability coefficient) ~6
&Hg. Several techniques for improving the film formability of this material and putting it into practical use have already been proposed and put into practical use. For example, Japanese Patent Application Laid-Open No. 51-89564,

。These poly-2- are easily soluble in aromatic solvents such as benzene, toluene, and xylene, and thin films can be easily obtained from solutions containing these polymers by conventional methods such as casting or water surface development. I can do it. The obtained thin film is transferred to a porous substrate and composited. Alternatively, a porous substrate may be impregnated with the polymer solution. However, the thin film thus obtained was found to have lower transmission properties than the original material. For example, to give a typical example, poly-1-methyl-2-trimethylsilylacetylene (molecular weight, about 1.2 million) polymerized in toluene using tantalum oxide has an initial value of permeability of P()2 =yx 1o-7cc -t

、酸素透過性にすぐれ、且つ酸素選択透過能の大きい気
体透過膜を得ることが出来た。It was found that one of the causes was the influence of various fillers present in the porous membrane used. In other words, it has been found that a strained polyacetylene having bulky substituents easily occludes molecules that are normally considered difficult to occlude. Moreover, it has been found that molecules that have been occluded remain stably present in the polymer unless they are extracted with a solvent that dissolves the molecules. Therefore, the present inventors used filtration fluoride, which has high oxygen solubility and is used in artificial blood, as the molecule to be occluded, and obtained a gas permeable membrane with excellent oxygen permeability and high oxygen selective permeability. I was able to do it.

らべ著しい特性向上が発揮された。Especially suitable were perfluorodecalin, perfluorolatrahydrofuran, perfluorotributylamine, etc., which are already used as artificial blood. The method for occluding these perfluorides in polyacetylene is not particularly limited, but includes dissolving the perfluoride and polyacetylene in a solvent such as a fluorine-containing vaporized hydrocarbon to form a mixed solution, It can be introduced by casting, or by exposing polyacetylene to perfluoride vapor. The content ratio of perfluoride to polyacetylene was 1 to 80%, preferably 2 to 45%. The perfluoride-containing polyacetylene composite membrane obtained in this way is stable due to the unique storage ability of the polyacetylene, and exhibits significantly improved properties compared to so-called liquid membranes made by impregnating other oxygen carriers into a porous membrane. It was done.
