Diffusion of a carbonate mixture in a poly(vinyl alcohol-co -vinyl acetate) in the solid state

Autor: Uwe Stebani, Jürgen Kaczun, Mohamed Taha, Amar Zerroukhi, Frédéric Becquart

Publikováno v: Polymer International. 53:412-419

The diffusion study of a carbonate mixture composed of ethylene and propylene carbonates in poly(vinyl alcohol-co-vinyl acetate) (PVA–Ac) was studied. The diffusion occurred in the solid state and the effect of the carbonate mixture on the PVA–Ac

Trends in applied macromolecular chemistry

Autor: Uwe Stebani, Peter Barghoorn, Martin Balsam

Publikováno v: Die Angewandte Makromolekulare Chemie. 267:1-9

In 1998 world-wide plastics production and consumption exhibited above average growth of 3,5 percent. Altogether approximately 158 million metric tons of polymeric materials were produced. Over the next few years plastics production is expected to gr

Liquid Crystalline Octahedral Iron(III) Complexes with 1,4,7-Tris[3,4-bis(decyloxy)benzyl]-1,4,7-triazacyclononane: Thermal Characterization and Mössbauer Investigations of Bridging and Redox Behavior

Autor: G. Henning Walf, Uwe Stebani, Günter Lattermann, Steven Schmidt, F. Jochen Litterst, Rüdiger Benda

Publikováno v: Chemistry - A European Journal. 4:93-99

The bridging behavior and redox mechanisms of liquid crystalline octahedral iron(III) complexes (such as the anhydrous complex below) were studied in detail by polarization microscopy, DSC, and Mossbauer spectroscopy. We gained great insight into the
