摘要：

PVE and PIP form simple van der Waals mixtures without any specific interactions. Nevertheless, as shown herein, their miscibility extends to infinite molecular weight of the components due to a negative interaction parameter. From the temperature dependence of x it is suggested that the sign of the noncombinatorial mixing free energy may have an enthalpic origin. A mechanism for this has been suggested. © 1992, American Chemical Society. All rights reserved.
