ON STRUCTURAL EFFECTS AND ENTROPIC FACTOR OF BLENDING NONCRYSTALLINE - POLYMERS WITH LIQUIDS

The absence of spontaneous blending of an amorphous polymer with a liq uid when their solubility parameters coincide is explained by specific features of the polymer supermolecular skeleton. Such a process requi res dissolving the structural skeleton and the availability of the suf ficient entropic-donor activity of the Liquid. Lack of the above activ ity rules out the spontaneous process. However, the possibility that t he process will take place via an indirect pathways remains because of the specific nature of supermolecular organization of polymer chains.
