Endothermic Effects on Heating Physically Aged Sucrose Glasses and the Clausius Theorem Violation in Glass Thermodynamics
Autor: G. P. Johari, Elpidio Tombari
Publikováno v: The Journal of Physical Chemistry B. 124:2017-2028
Experimental heat capacity, Cp,app, of some physically aged polymers had shown an endothermic peak or a shoulder on heating when the material was still in the glassy state. In the first part of thi...

When glasses formed by cooling at different rates are heated at the same rate, they show different shapes of the glass to liquid transition endotherm in their C-p-T plot and different onset temperatures of the C-p-endotherm. (This temperature is take

A statistical mechanical model previously adopted for the analysis of the α-relaxation in structural glass formers is rederived within a general theoretical framework originally developed for systems approaching the ideal glassy state. The interplay

Dielectric relaxation of thermotropic liquid crystalline polyesters based on α,ω,-alkylene-di-4-hydroxybenzoates and 4,4’-alkylenedioxy-dibenzoic acid
Autor: Giancarlo Galli, Giuseppe Salvetti, Emo Chiellini, Elizabeth Grillo Fernandes, Elpidio Tombari
Two structurally isomeric homologous series of semiflexible thermotropic liquid crystalline polyesters were analysed by dielectric spectroscopy in temperature intervals varying from 253 to 403 K. Each series is characterised by a well-distinct behavi
