Dibenzazepine derivatives were added to epoxy resin (bisphenol A diglycidyl ether, DGEBA). DSC analyses showed that DGEBA could be cured by the addition of secondary and tertiary alkylamine type compounds, but not by the addition of N-butoxycarbonyl substituted compound. Curing of the cast film and adhesion of glass substrates by dibenzazepine-containing polymers/DGEBA mixture was also observed. Therefore, the fluorescence spectra of dibenzazepine-containing polymers in DGEBA were compared. When the polymer was blended with DGEBA and the mixture was heated, the fluorescent λmax changed. This spectral change depended on the substituent of the polymer. This fluorescent behavior suggests that the polymers are likely to be monitoring agents for curing and adhesion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
