    Description / Table of Contents: Neue Diglycidylester wurden in Gegenwart von quaternären Ammoniumsalzen als Katalysator aus ihren entsprechenden Dicarbonsäuren und Epichlorhydrin hergestellt. Die neuen unsymmetrischen Produkte wurden durch spektroskopische Methoden identifiziert und als Monomere in einer Aushärtungsreaktion eingesetzt. Der Reaktionsverlauf wurde mittels IR-Spektroskopie verfolgt. Die Struktur einiger 1öslicher Zwischenprodukte wurde durch 13C-NMR-Spektroskopie ermittelt. Das thermische Verhalten dieser ausgehärteten Epoxidharze wurde ebenfalls untersucht.
    Notes: New diglycidyl esters coming from the corresponding diacids and epichlorohydrin were synthetized using a quaternary ammonium salt as a catalyst. The new asymmetric compounds were characterized by spectroscopic methods and employed as starting monomers in a crosslinking process. The course of the reactions was followed by IR spectroscopy. Some intermediate species were identified in the onset of the reactions by recording 13C-NMR spectra until the products became insoluble in the usual deuterated solvents. The thermal behaviour of these cured epoxy resins was also studied.
