Using the wide-angle X-ray method and thermomechanical analysis method, the structure and thermomechanical properties of nanocomposites formed from interpolyelectrolytemetal complexes (IMC) are investigated. As revealed, the chemical reduction of Cu2+ cations in interpolyelectrolytemetal complexes pectinCu2+P4VP with use of NaBH4 takes place with formation of nanocomposite based on the interpolyelectrolyte complex (IPEC): pectinP4VP and Cu/Cu2O coreshell nanoparticles. The method of thermomechanical analysis shows that, during the transition from IPEC and IMC to nanocomposite IPECCu/Cu2O, the glass-transition temperature, Tg, and the temperature of transition into viscous state, Tf, are increasing. This indicates a higher thermal stability of nanocomposite comparing with the IPEC and IMC systems.
