Summary
The interaction parameter for isotopic mixtures of poly(vinylethylene) was determined from small angle neutron scattering measurements to vary from 6.6×10−4 to 5.7×10−4 over a temperature range of from just above Tg to 71°C. The phase behavior of these blends differs significantly from the predictions of Flory-Huggins theory, indicating that, in addition to their non-ideality, polymer isotopes do not form simple mixtures. This phase behavior, however, was found to be congruent with the symmetrical model of mixtures.
