Resumen
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 (Tm) depression for the blends allowed determination of the Flory-Huggins interaction parameter (cursive Greek chi12) of the two polymers in the melt using the Nishi-Wang equation. The Hoffman-Weeks extrapolation was applied to obtain equilibrium Tm data. The values of the cursive Greek chi12 obtained from Tm depression data were negative for all blends. This suggests the miscibility of the components of the blends. © 1998 Published by Elsevier Science Ltd. All rights reserved. 39 12 2551 2556 Nishio, Y., Haratani, T., Takahashi, T., (1990) J. Polym.
