The complete similarity of reinforcement degree behaviour has been shown for nanocomposite epoxy polymer/Na+-montmorillonite and polyarylate, which is considered as the natural nanocomposite. The polyarylate structure description is given within the framework of cluster model of polymers amorphous state structure. The interfacial adhesion level influences strongly the reinforcement degree of indicated materials.

The structural treatment of amorphous glassy polycarbonate as natural nanocomposite was proposed. It has been shown that the polycarbonate stiffness is defined completely by the state of its structure, which is described within the frameworks of a local order model. The large reserves of stiffness raising for amorphous glassy polymers are demonstrated.

Thermal and thermo-oxidative degradation, as well as crosslinking and "curing" processes of polyphenylene sulfide, depending on the heat treatment regimes, have been studied using gas chromatography. The effect of sorbed water in the polymer on the processes of thermal and thermo-oxidative decomposition of polyphenylene sulfide is shown and the optimal modes of drying the samples are established.
