Summary
The binding equilibrium of sodium dodecyl sulfate (SDS) to poly(ethylene oxide) in 0.1 M sodium chloride solution at 30°C was determined by using a dialysis technique. The binding isotherm was characterized by a sudden uprise near 1 mM SDS and a saturation tendency towards the cinc (1.5 mM).
The completion of binding in such a narrow concentration range is attributable to a strong cohesion between bound surfactant molecules, and to a smallness of the surfactanr cluster which is considered as distributed along the polymer chain.
Zusammenfassung
Es wurden die Bindungsgleichgewichte des Natriumdodecylsulfats mit Poly(äthylenoxyd) in 0.1 M Natrium-chlorid-Lösung bei 30°C durch die Dialysemethode bestimmt. Die Bindunsisotherme werden von der plötzlichen Zunahme nahe 1 mM Tensid und der Sättigungstendenz zu der cmc (1.5 mM) charakterisiert. Es wurde gefolgert, daß das Zustandekommen der Bindung in einem so engen Konzentrationsberich der starken Kohäsion zwischen den gebundenen Tensidmolekülen und der Kleinheit des Tensidbüschels, welches längs der Polymerkette werteilt ist, zugeschrieben werden kann.
