Morphological modification occurring in poly-ether-ether-ketone (PEEK) during crystallization, the chemorheological behaviour of an unsaturated thermosetting polyester and the hygrothermal stability of epoxy and polyurethane based composites has been investigated. An Avrami approach has been adopted in order to interpret the dual mode cold crystallization of the amorphous PEEK based on dielectric, differential scanning calorimetry and dynamic-mechanical analyses. The correlation between dielectric measurements, viscosity and degree of cure during the polymerization of a thermoset is discussed. Finally, the hygrothermal stability of epoxy and polyurethane based composites is analysed in terms of dielectric modifications.

Crystallization behaviour involving high mobility Be, Cu and Ni atoms, which results in multiple peaks exotherm in isothermal DSC annealings, has been observed in bulk metal glassy supercooled liquids. Experimentally measured increases of the temperature needed to induce the glassy metal relaxation (glass transition) in selectively crystallized samples have been experimentally determined. DSC dynamic investigation indicated that three atomic elements present in the metastable liquid were involved in recrystallization process below 450-470°C. Isothermal annealing in the range of temperatures between 400° and 450°C has been chosen for further investigation on thermal events kinetics occurring in the super-cooled liquid.
