The miscibility of the dicyanate of bisphenol A, with three dicyanate monomers, with aryl/alkylene ether backbones is studied at different compositions of a binary blend. Solubility parameters are calculated for dicyanate monomers and selected oligomers using the methods of Small and Fedors to predict compatibility. The results are evaluated in terms of the accuracy of the model in reproducing observed data. Gibbs free energy of mixing (ΔGmix) values for selected blends are calculated using the BLENDS module of Cerius2. Empirical data (HPLC and MS) are used to inform the construction of selected models to represent different stages of polymer conversion. DMTA analysis is performed to examine the thermo-mechanical properties of the resulting blends and compared with the simulated blend data.
