Physical and Mechanical Behavior of Polymer Glasses in Terms of Temperature-Induced Relaxation of Plastic Deformation

Temperature-induced relaxation of residual plastic deformation of polymer glasses was discussed in terms of structural inhomogeneity of glassy polymers. Mechanical properties of glassy polymers were shown to be controlled by the ratio between low-temperature and high-temperature components of temperature-induced relaxation of residual deformation. This ratio was treated as a new physical parameter describing physical and mechanical behavior of polymer glasses. The applied aspects of studying temperature-induced relaxation of residual deformation concerning the prepartion of modern polymer materials were discussed.
