STRUCTURAL AND ENTROPIC EFFECTS OF BLENDING POLYMERS WITH LIQUIDS

The absence of spontaneous blending of an amorphous polymer with a liq uid, when their solubility parameters coincide, is explained by a spec ific feature of the polymer supermolecular skeleton. The process of sp ontaneous blending requires dissolving the supermolecular skeleton and takes place only under the sufficient entropy-donor activity of the L iquid. The lack of this activity rules out the spontaneous process. Ho wever, the compatibility does occur via indirect pathway when stimulat ing a proper excitation or disintegration of a supermolecular carcass. (C) 1998 John Wiley & Sons, Inc.
