✦ Synopsis

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.

A~tract--Mechanical properties of blends of nylon-6 with a liquid crystal copolyesteramide (LCP) are presented. The improvement of the elastic modulus increases with increasing the draw ratio. Fibrils of LCP are evident when the draw ratio >40. The moduli are lower than those predicted by the theory
