Studies on adsorption of a copolymer at air/water-and at oil/water-interfaces

The interfacial properties of a synthetic copolymer have been investigated, both at air/water (A/W) and at oil/water (O/W) interfaces, utilizing modified WILHELMY plate method. The number average molecular weight and the thermodynamic parameters have been evaluated. The increased flexibility of the...

Description
Summary:The interfacial properties of a synthetic copolymer have been investigated, both at air/water (A/W) and at oil/water (O/W) interfaces, utilizing modified WILHELMY plate method. The number average molecular weight and the thermodynamic parameters have been evaluated. The increased flexibility of the macromolecular chain at oil/water interface has been observed. Die Oberflächeneigenschaften eines synthetischen Copolymeren wurden nach der modifizierten WILHELMY‐Methode an Luft/Wasser und an Öl/Wasser untersucht. Das Zahlenmittel des Molekulargewichts und die thermodynamischen Parameter wurden ermittelt. Eine erhöhte Flexibilität der Makromoleküle an der Öl/Wasser‐ Oberfläche wurde beobachtet.
