Blends of poly(ethylene) oxide with poly(epichlorohydrin) and poly(epichlorohydrin-co-ethylene oxide) have been prepared by the freeze-drying method from benzene solutions of the polymer mixture at different compositions. The miscibility of the mixtures was studied by DSC. A single glass transition temperature is observed for all the blends studied. Measurement of the melting temperature (T-m) depression for the blends allowed determination of the Flory-Huggins interaction parameter (chi(12)) of the two polymers in the melt using the Nishi-Wang equation. The Hoffman-Weeks extrapolation was applied to obtain equilibrium T-m data. The values of the chi(12) Obtained from T-m depression data were negative for all blends. This suggests the miscibility of the components of the blends.
