Verhalten polyvalenter Fadenmolekelionen in Lösung
Abstract
Bei Zusatz von Alkali zu einer sehr verdünnten Lösung von Polymethacrylsäure in Wasser tritt eine starke Steigerung der spezifischen Viskosität auf. So steigt ν sp bei einer wässerigen Lösung von Polymethacrylsäure vom Polymerisationsgrade Z = 650 um einen Faktor 130, wenn die Hälfte der in der Molekel vorhandenen COOH‐Gruppen durch Zusatz von Alkali aus dem nicht ionisierten in den ionisierten Zustand übergeführt werden. Ausser dem Einfluss des Ionisierungsgrades auf die spezifische Viskosität ist auch der Einfluss auf Betrag und Orientierung der Strömungsdoppel‐brechung sowie auf die Depolarisation des Streulichtes festgestellt worden.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
