Summary

Surface tension has been measured of polyacrylic acidwater solutions with pH 3–11. Until approximately pH 4.6 corresponding to 10% neutralization, PAA-solutions are surface active and inactive at higher pH, time dependence of equlibrium surface tension is analysed. Non-ionized “neutral” chain segments are surface active, their diffusion to surface is rate determining.

Zusammenfassung

Es wurde die Oberflächenspannung von wäßrigen Polyacrylsäure-Lösungen der pH-Werte von 3–11 gemessen. Bis zu einem pH-Wert von etwa 4.6, d. h. 10% Neutralisation, sind die Lösungen oberflächenaktiv, bei höheren pH-Werten inaktiv. Es wird die Zeitabhängigkeit der Einstellung der Gleichgewichtsoberflächenspannung analysiert. Nicht ionisierte, „neutrale” Kettensegmente sind oberflächenaktiv. Diffusion zur Oberfläche ist der zeitbestimmende Faktor.
