Summary
The present light scattering measurements reaffirm the fact that the polyethylene glycol molecules are associated in aqueous solution through the formation of both intra- and inter-molecular hydrogen bonds. The rupture of such association by the addition of either urea or thiourea is also noticed.
Zusammenfassung
Die hier vorliegenden Lichtstreuungsmessungen bekräftigen die Tatsache, daß Polyäthylenglykol-Moleküle in wäßrigen Lösungen durch Bildung von intraund inter-molekularen Wasserstoffbrücken assoziiert sind. Durch Hinzufügen von Harnstoff und Thioharnstoff brechen diese Brücken auf.
