    摘要： An ion exchangeable mixture containing a polymeric compound consisting of an ion exchange resin, an acrylamide mixture containing at least one bisacrylamide and at least one acrylamide, and a copolymer obtained by reacting the polymeric compound with the acrylamide mixture, and a method of producing the same are provided. The ion exchangeable membrane produced by using the ion exchangeable mixture has significantly smaller electric resistance than conventional ion exchangeable membranes, and has excellent selective permeability because the ion exchangeable membrane is electrically charged. The ion exchangeable membrane can be produced under very mild production conditions, and thus can be produced very easily. Furthermore, the ion exchangeable membrane can be also formed into film during a crosslinking reaction in a solvent of water, and thus is advantageous in that the ion exchangeable membrane can be freely produced into desired sizes, shapes and forms.

    摘要： New diphosphonic acid diesters in which the two phosphorus atoms are bound by a hydrocarbon group while each of the two acid functions of the diphosphonate is esterified by a radical having at least three carbon atoms are prepared by the treatment with a weak base of a corresponding tetramethyl diphosphonate, thereupon replacement of the cations of the base in the resultant disalt, by a radical R by means of a halide of said radical, and finally hydrolysis of the mixed diphosphonate thus obtained. The new compounds are suitable for various known uses of the different diphosphonates and in particular for the complexing of heavy metals; they are used in particular for the extraction of uranium and metals associated with it.
