The structural mechanism of polymer nanocomposites filled with organoclay on a suprasegmental level was studied. Within the framework of this mechanism, the nanocomposites elasticity modulus is defined by local order domains (nanoclusters), with sizes similar to natural nanocomposites (polymers). Densely-packed interfacial regions which form in nanocomposites at nanofiller introduction is the physical basis of decrease in the size of nanoclusters.

It has been shown that at semicrystalline polymers with devitrificated amorphous phase consideration as natural hybrid nanocomposites their anormalous high reinforcement degree is realized at the expence of crystallites partial recrystallization (mechanical disordering), that means crystalline phase participation in these polymers elastic properties formation. It is obvious, that the proposed mechanism is inapplicable for the description of polymer nanocomposites with inorganic nanofillers.
