Abstract
Glasses can be formed in numerous ways, involving very different microscopic processes. This article reviews some recent results on chemical vitrification, a process where the slowdown in the dynamics of a liquid is controlled by the irreversible formation of chemical bonds. Making a connection between the reduction in configurational entropy and the number of chemical bonds, the dynamics of vitrification in chemically reactive systems is explained in terms of their configurational restrictions in the same manner as in stable glass-forming liquids under cooling or compression.File in questo prodotto:
