    Description / Table of Contents: Die Aufnahme von Ag(I)-Ionen durch Sorptionsmittel, die Ethylendiamin- (en) und Iminodiacetat-Gruppen (ida) enthalten, wurde untersucht. Die Trägersubstanzen waren makroporöses Glas, das auf seiner inneren Oberfläche mit Polyglycidylmethacrylat (glass-GMA) überzogen war, Glycidylmethacrylat-Ethylendimethacrylat-Copolymerisat (GMA-EDMA) und GMA-EDMA eingekapselt in Poly-2-hydroxyethylmethacrylate. Die Sorptionsgeschwindigkeit von Cu(II) nahm in mit en modifizierten Sorptionsmitteln in der gleichen Reihenfolge ab. Für die Sorption von Ag(II) wurdeein Sorptionsmittel durch Reaktion von GMA-EDMA mit 3-Aminopyndin herge-stellt; die Sorption wurde in oxidierender Lösung durchgeführt. Die bei der Sorption gebildeten Komplexe wurden in allen Fällen spektroskopisch aufgeklärt.
    Notes: The sorption of Ag(I) ions on sorbents containing ethylenediamine (en) and iminodiacetate (ida) groups was investigated. The basic backbone consisted on macroporous glass coatd on its inner surface with poly(glycidylmethacrylate) (glass-GMA), copolymer glycidylmethacrylate-ethylenedimethacrylate (GMA-EDMA), and GMA-EDMA encapsulated in poly(-2-hydroxyethylmethacrylate). The rate of sorption of Cu(II) in sorbents modified with en decreased in the same order. For the sorption of Ag(II), a sorbent was synthesized by a reaction of GMA-EDMA with 3-aminopyridine, and the reaction with the ion was carried out in an oxidizing solution. The types of complexes formed in the sorption were determined spectroscopically in all cases.

    Description / Table of Contents: An porösem Glas sorbiertes 2,3-Epoxypropylmethacrylat wurde radikalisch polymerisiert. Die Polymerisations-bedingungen wurden so gewählt, daß das erhaltene Polymer linear bzw. nur sehr schwach vernetzt war. Die Polymermenge auf dem Glas kann durch Verdünnen der Polymerisationsmischung oder durch Variation der auf dem Glas befindlichen Wassermenge variiert werden. Die spezifische Oberfläche des Systems nimmt mit steigendem Polymergehalt ab. Mit zunehmender Oberfläche des porösen Glases, d. h. abnehmendem Durchmesser der Poren, steigt die Menge des an das Glas gebundenen Polymers ebenfalls an.
    Notes: 2.3-Epoxypropyl methacrylate sorbed on porous glass was polymerized by radical mechanism. The polymerization conditions were chosen so that the polymer obtained was linear or only very slightly crosslinked. The amount of the polymer on glass can be varied arbitrarily by diluting the polymerization mixture or by varying the amount of water on glass. The specific surface of the system decreases with increasing polymer content. With increasing specific surface of porous glass, i. e. with decreasing diameter of the pores, the amount of the polymer bound on glass also increases.

    Description / Table of Contents: Mittels 1H- und 13C-NMR- sowie Ramanspektren wurde gezeigt, daß die Epoxidgruppe von 2,3-Epoxypropylmeth-acrylat (EPMA) in Gegenwart einer großen Glasoberfläche quantitativ gespalten wird, wobei es zur Bildung von 2,3-Dihydroxypropylmethacrylat und einer Reihe von niedrigmolekularen Substanzen mit Doppelbindungen kommt. Die Polymerisation von EPMA in Gegenwart von porösem Glas liefert Poly(2,3-epoxypropyl-methacrylat). Ein Teil dieses Polymers ist am Glas fest gebunden, wahrscheinlich über die Zerlegungsprodukte des EPMA.
    Notes: From 1H- and 13C-NMR and Raman spectra it was found that by the presence of a large surface of glass, the epoxide group of 2,3-epoxypropyl methacrylate (EPMA) is completely decomposed, yielding 2,3-dihydroxypropyl methacrylate and a number of additional low-molecular-weight products with double bonds. Polymerization of EPMA in the presence of porous glass yields poly(2,3-epoxypropyl methacrylate). Part of this polymer is firmly bound to the glass, probably by means of the decomposition product of EPMA.

    Notes: The experimental and clinical use of perfusion of blood or plasma through polymer-coated adsorbents in several liver diseases is described. Altogether, 148 clinical perfusions were performed. The best results were obtained in severe cholestasis, liver coma and two types of hepatic porphyrias.

    Reactive polymers. XLI. Preparation of poly(2,3-epoxypropyl methacrylate) on silica gel (1981)

    Description / Table of Contents: An Silicagel sorbiertes 2,3-Epoxy-propyl-methacrylat wurde nach Zugabe von 1,4-Dioxan und einem Initiator radikalisch polymerisiert. Dabei entstand eine an der Silicageloberfläche fest fixierte polymere Schicht. Die Polymermenge kann man durch Verdünnung des Polymerisationsgemisches weitgehend regulieren. Spezifische Oberfläche und Porenvolumen nehmen bei Anstieg des Polymergehaltes ab. Mit wachsender spezifischer Oberfläche des Ausgangsilicagels wächst auch die Menge des gebildeten Polymers. Durch die Dauer der Monomersorption am Silicagel sowie durch Trocknung des Silicagels bei 100°C vor der Sorption wird die Menge des gebildeten Polymers nicht beeinflußt. Einen deutlichen Einfluß auf die Menge und die chemische Zusammensetzung der Polymerschicht hat jedoch eine Erwärmung auf eine Temperatur von 200 bis 800°C.
    Notes: 2,3-Epoxypropyl methacrylate sorbed on silica gel was radically polymerized after addition of 1,4-dioxan and initiator. A polymeric layer was formed which was firmly fixed on the silica gel surface. The amount of the polymer on silica gel can be controlled within a wide range by diluting the polymerization mixture. The specific surface area and the specific pore volume in the system decrease with increasing polymer content. The content of the polymer formed increases with increasing specific surface area of the initial silica gel. The amount of the polymer formed remains unaffected by a change in sorption time of the monomer on silica gel and by additional drying of silica gel at 100°C before the sorption of the monomer. Heating of the initial silica gel to 200-800°C has a basic influence on the content and chemical composition of the polymeric layer.
