, N, the reproducibility of the product PEC is poor. PVSK is also 5g/! for the same reason! ! The following concentrations are preferred. Also, the reason why p)[ of the acid aqueous solution of PAC and PVStC was set in the range of 1.0 to 4.3 is because pl(1
, less than 0, PEC exists in solution and no precipitate is formed; conversely, if it exceeds pi (43), a precipitate of AI!(OH)3 is formed and PEC cannot be formed. The type of acid used at this time is not particularly limited, and may be either an inorganic acid or an organic acid as long as it does not react with PVSK.

Therefore, in order to avoid raising the temperature too much during dehydration and drying of the PEC as a precipitate, the PEC should be washed with a highly volatile alcohol system and dried in a low temperature range.
〈実施例〉 以下本発明をその実施例を示し乍ら更に詳述する。<Example> Hereinafter, the present invention will be described in more detail while showing examples thereof.

の早さで滴下し沈殿を得た。In this example, aqueous solutions of P person C and PVSK were prepared with a pH range of 1.0 to 4.0 using an aqueous hydrochloric acid solution, and the solutions with the same pif value were heated at a constant temperature of 23°C. Add one solution to the other 50ml/'30mln
The solution was added dropwise at a rate of 100 to obtain a precipitate.

みを以下の実験に供した。Immediately after generation, PEC is unstable, so it is left standing for 30 minutes, centrifuged, washed with methanol, and dried under reduced pressure at room temperature until it reaches a constant weight. Only those with an error in the amount produced within 3% of the average value are It was used in the following experiments.

An example in which a solution was dropped into a PVSK solution. Similarly, 2 shows an example in which a PVSK$ solution was dropped into a PAC solution.
Depending on the order of dropping the solution or the PVSK solution, there is a difference in the amount dropped from the aggregation start point to the aggregation end point. To make this easier to understand, the horizontal axis is the npt+ value, and the vertical axis is the nipt+ value.
The graph shown in the figure is a graph obtained by taking the % ratio, and in this figure, O2Δ is .
On the other hand, when the PAC solution is added dropwise, 0.・ indicates the starting point of aggregation, and Δ and Mu indicate the ending point of aggregation.

It will be done. The actually obtained PEC is pl(
The fact that it was a viscous substance at pH 2.0 or less, and a smooth powder at pH 4.0, is also considered to support the difference in PEC obtained when the pH is different.

である。<Effects of the Invention> As described above, according to the present invention, it is possible to obtain an electrolyte complex consisting of a novel inorganic-organic combination that is completely different from conventional organic polymer electrolyte complexes. The product has better active transport properties and permselectivity than conventional organic materials, and is particularly resistant to acids and alkalis, as well as being electrically conductive. It can be used in a wide range of new applications, such as applications that require chemical resistance and conductivity, as well as applications for various functional substances that previously used organic materials. be.
