Relaxation transitions in polyvinylchloride containing a nanodispersed material

Results of experimental investigations and evaluations of the influence of the microstructure of polyvinylchloride macromolecules on relaxation processes in heterogeneous systems containing nanodispersed copper powders have been given. It has been shown that the relaxation β transition whose parameters are dependent on the content of the filler in the composite is realized in the region 300 K ≤ T < 400 K. The interrelation between the β transition and the cooperative glass α transition has been established. A derivatographic analysis of the distinctive features of the process of splitting of the α maximum with allowance for the degree of ordering of the arrangement of segments in the composite volume has been made. Calculated and experimental values of the sought quantities have been compared.
