Water contents, ion-exchange selectivity coefficients, and specific electrical conductances of phosphate monoester (PME) and phosphate diester (PDE) cation-exchange resins are measured. The group 1 cation forms contain the most water (e.g., 39.2% for Na+-PME and 28.8% for Na+-PDE), while the hydrogen and polyvalent cation forms have the lowest water contents (e.g., 24.9% for Ca2+-PME and 17.9% for H+-PDE). The selectivity coefficients for eight cation-pair systems on the PME resin and three cation-pair systems on the PDE resin are determined. The resins exhibit high selectivities for the proton and polyvalent cations (e.g., log ffHNa = 0.98 for PME and log 7fMgNa = 1.42 for PDE). The specific electrical conductances for four ionic forms of each resin are measured, the Na+ forms exhibiting the highest values (e.g., 5.0 X '3 "1 cm"1 for Na+-PME) and the divalent forms having much lower values (e.g., 2.4 X "4 "1 cm"1 for Cu2+-PDE).

Vorliegende Arbeit wird als eine Weiterentwicklung des bisherigen Standes der molekularen Informationstheorie, der molekularen Epitaxieversuche und der Silikagelprägungen durch Dickey sowie Erlenmeyer und Bartels charakterisiert.Es wurden Phenol‐Formaldehydharze, die zum Teil mit Melamin dotiert waren, mit Cu‐Phthalozyanintetrasulfosäure geprägt.Das “Wiedererkanntwerden” dieser Säure durch das Harz wurde durch Aufnahme von Adsorptionsisothermen mit Hilfe der “progressive batch”‐Methode und des Spektrometers geprüft.Die erhaltene Prägung erwies sich in bezug auf diese Tetrasäure als besonders spezifisch im Vergleich zu einer Monosäure.Die Informationsgleichung für die Größe der Prägung wurde statistisch abgeleitet. Mit Hilfe dieser Gleichung wurde die Größe der Prägung in natürlichen Informationseinheiten aus den graphisch gewonnenen Daten berechnet.
