摘要：In the last decade the challenging analysis of previtreous behavior of relaxation time ( τ ( T )) in ultraviscous low molecular weight liquids led to the conceptual shift of the glass transition physics toward theories not predicting a “ finite-temperature ” divergence. This “breakthrough” experimental finding was strengthened by the discovery that “ dynamic ” (i.e. from τ ( T ) fitting) and “ thermodynamic ” estimations of the “ ideal glass ” (Kauzmann) temperature do not match, what in fact questioned its existence. In this report, due to the novel way of analysis based on the transformation of τ ( T ) experimental data to the activation energy temperature index form, the clear prevalence of the “ finite-temperature ” divergence is proved. The obtained “ dynamic ” singular temperatures clearly coincide with “ thermodynamic ” estimations of the Kauzmann temperature, thus solving also the second mystery. The comprehensive picture was obtained due to the analysis of 55 experimental data-sets, ranging from low molecular weight liquids and polymers to liquid crystal and plastic crystals.
