Title

Modellreaktionen und Modellharze auf Epoxidharze

Abstract
With a monofunktional epoxy compound the reaction behaviour of cold curing epoxy resins was simulated and then investigated with thin layer chromatography (TLC). The monomer reaction products allow mass- and NMR-spectroskopical analyses which show that only secondary Beta-aminoalcohols are formed. The model epoxy reacts with primary amines in three steps due to the different nucleophilicity of each functional group. This fact directly leads to postcuring epoxy hot-melts. At room temperature a thermoplastic polymer with adhesional properties is formed, which can be post-cured at higher temperatures into a duromer resin.
