| Popis: | A solid-state NMR dipolar dephasing experiment is constructed to probe the phase morphology of isotopic blends of poly(vinylethylene). It is demonstrated that the blend is segmentally mixed for component molecular weights at which the critical value of the interaction parameter, as calculated using the Flory-Huggins lattice model, is less than the actual interaction parameter of the blend. |
