E. Pedemonte et G. Burgisi, THERMODYNAMICS OF POLY(ETHYLENE OXIDE) POLY(METHYL ACRYLATE) BLENDS -PREDICTION OF MISCIBILITY BASED ON THE PRIGOGINE-FLORY THEORY, Polymer, 35(17), 1994, pp. 3719-3721
The misicibility of poly(ethylene oxide) (PEO) with poly(methyl acryla
te) (PMA) is demonstrated by using the Prigogine-Flory theory in Patte
rson's approximation. Negative values of enthalpy of mixing, contact-e
nergy term and interaction parameter were obtained for the blend with
75/25 weight ratio. The temperature dependence of chi12/V1 indicates
that PEO-PMA mixtures are miscible in the liquid state over the access
ible temperature range.
