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 an N-butoxycarbonyl substituted compound. Curing of the cast film and the adhesion of glass substrates by a 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.

环氧树脂中含二苯并氮杂的聚合物的荧光行为

将二苯并氮杂衍生物添加到环氧树脂(双酚 A 二缩水甘油醚,DGEBA)中。DSC 分析表明 DGEBA 可以通过添加仲和叔烷基胺类化合物来固化,但不能通过添加N-丁氧基羰基取代的化合物来固化。还观察到含二苯并氮杂的聚合物/DGEBA混合物对流延膜的固化和玻璃基材的粘附。因此,比较了 DGEBA 中含二苯并氮杂聚合物的荧光光谱。当聚合物与 DGEBA 混合并加热混合物时,荧光 λ max发生变化。这种光谱变化取决于聚合物的取代基。这种荧光行为表明聚合物可能是固化和粘附的监测剂。
