The absence of spontaneous blending of an amorphous polymer with a liquid, when their solubility parameters coincide, is explained by a specific feature of the polymer supermolecular skeleton. The process of spontaneous blending requires dissolving the supermolecular skeleton and takes place only under the sufficient entropy–donor activity of the liquid. The lack of this activity rules out the spontaneous process. However, the compatibility does occur via indirect pathway when stimulating a proper excitation or disintegration of a supermolecular carcass. © 1998 John Wiley & Sons, Inc.
