Competition Between Crystallization and Glass-Transition Processes in Binary Amorphous Molecular Systems

摘要

Crystallization and glass transition phenomena of binary amorphous molecular systems were studied as the function of composition. For chlorobenzene/toluene and chlorobenzene/ethylbenzene systems, it was found that the temperatures of direct crystallization and glass transition from the amorphous state and the temperature of crystallization from supercooled liquid state come across each other in a certain region of composition, where the three processes are considered to compete with each other. Molecular motions related to these processes are discussed on the basis of the structure of crystals that appear as the results of the annealing of the samples.
