The morphology of the diglycidyl ether of bisphenol-A / poly(3-aminopropylmethylsiloxane) (DGEBA/PAMS) reactive blends was studied by fluorescence techniques as a function of the initial composition. Some fluorescence results were compared with those from optical and electron microscopy investigations. Several morphological aspects were studied including the distribution of PAMS in the blend. The microsegregation of PAMS was discussed in terms of diffusion restriction of DGEBA through the PAMS dispersed phase.
