    Description / Table of Contents: Es wurde die Dispersion von Solen einiger übergangsmetalle (Gold, Eisen(III)-oxid · H2O, Chromhydroxid) in einem wasserlöslichen Polymeren (PVA 4-88) untersucht und von den daraus hergestellten Filmen ein Vergleich ihrer mechanischen und elektrischen Eigenschaften gemacht. In Erweiterung auf nichtwäßrige Lösungsmittel (Dimethylformamid, Tetrahydrofuran) wurden die Wechselwirkungen von mehrwertigen Metallionen (Fe(III), Al(III), Ti(IV), Zr(IV), Pd(O), Ag(O), Au-Sole) mit einem spezifischen metallkomplexierenden Polymeren (Polyacrylamidoxim) und einem Blockcopolymeren, das Styrol und Butadien (Buna BL 6533) enthält, untersucht.
    Notes: The dispersion of transition metal sols (gold, ferric hydrous oxide, chromium hydroxide) in a water soluble polymer (PVA 4-88) was investigated and from the films produced, a comparison made of their mechanical and electrical properties. Extending to non aqueous solvents (dimethylformamide, tetrahydrofuran) interactions of polyvalent metal ions (Fe(III), Al(III), Ti(IV), Zr(IV), Pd(0), Ag(0), Au sols) with a specific metal complexing polymer (poly(acrylamideoxime)) and a block copolymer containing styrene and butadiene (Buna BL 6533) were investigated.

    Notes: The approach of Karfunkel and Gdanitz has been used to predict possible crystal structures of acetic acid and three of its monohalogenated analogs starting with the molecular structure alone. The results demonstrate that this approach is capable of finding many, if not all, of the possible packing arrangements of molecules of this size, but that it is not currently capable of correctly ranking these structures in terms of their enthalpy. This deficiency is probably due to inadequacies in the force field used to minimize the structures. The inadequacies relate to the description of acidic hydrogen bonds and halogen-halogen interactions.   © 1998 John Wiley & Sons, Inc.   J Comput Chem 19: 1-20, 1998
