Abstract

Based on the concept of polymer-polymorphoid structure of glass and glass-forming liquids the experimental data related to the structure and relaxation processes, in particular, the glass transition in chalcogenide and oxide and halogenide glassforming substances are analyzed. This has been demonstrated that all the relaxation processes in liquid and glassy state have a common physicochemical nature - the mutual conversion of the structure fragments (polymorphoids) of the different crystalline polymorphic modifications without the translational symmetry (long-range order), copolymerized to a greater or lesser degree, respectively, in the vitreous or liquid state..
