The viscoelastic properties of an in‐situ compatibilized thermoset/thermoplastic blend were investigated. A reverse mechanical modeling was used to predict (1) the actual viscoelastic characteristics of the in‐situ synthesized interphase in the blend and (2) the evolution of these actual characteristics as a function of the thermal history of the polymer blend. Thus, predicted data revealed a significant increase of the ability of the molecular mobility in the interphase area after a refreshing thermal treatment be applied to the blend. Lastly, the frequency dependence of the predicted relaxation of the interphase component was also studied.
