    Description / Table of Contents: Gel permeation chromatography and thin layer chromatography have been used respectively to separate and characterize the first seven members of an epoxy resin polymer homologous series on a preparative and analytical scale. The epoxy resin was formed by the reaction between Bisphenol-A and epichlorhydrin. NMR was used to identify the oligomers. The relationship between extinction coefficient and degree of polymerisation was also determined.
    Notes: Zur näheren chemischen und spektroskopischen Charakterisierung wurden die ersten sieben polymerhomologen Glieder der Reihe der Epoxidharze aus Bisphenol A und Epichlorhydrin mit Hilfe der Gel- und Dünnschichtchromatographie analytisch und präparativ getrennt. Die Oligomeren wurden mittels NMR-Spektroskopie identifiziert. Der Zusammenhang zwischen Extinktionskoeffizient und Polymerisationsgrad wurde ermittelt.
