    Description / Table of Contents: Zusammenfassung Wässerige Suspensionen und Emulsionen, die durch nichtionogene Tenside vorn Polyoxyäthylentyp allein stabilisiert sind, werden durch Zusatz polymerer Säuren (z. B. Polyakrylsäure) und Elektrolyten (Säure und neutrale Salze polyvalenter Kationen) geflockt. Die destabilisierende Wirkung der polymeren Säuren wird der Wechselwirkung zwischen der Polymersäure und dem nichtionogenen Tensid zugeschrieben. Einige Beispiele für die Flockungsreaktion werden mitgeteilt.
    Notes: Summary Aqueous suspensions and emulsions stabilized solely by nonionic surfactant of the polyoxyethylene type are flocculated by adding polymeric acid (for example, poly-acrylic acid) and electrolyte (acid and neutral salts of polyvalent cations). This destabilization effect of polymeric acids is ascribed to the interaction between the polyacid and nonionic surfactant on the colloid particles. Some examples of the flocculation reaction are shown.
