The field of viscous liquid and glassy solid dynamics is reviewed by a process of posing the
key questions that need to be answered, and then providing the best answers available to …

Exposure to extended periods of sub‐Tg temperatures causes physical changes in the
molecular structure of epoxy resins and epoxy‐based materials to occur. These physical …

Polymer ageing may involve physical ageing without chemical reaction occurring; chemical
changes such as crosslinking during curing of a thermoset; thermal conditioning at elevated …

Volume and enthalpy recovery measurements were used to study the physical aging
behavior of a polystyrene. Isothermal aging at temperatures near Tg was studied with aging …

There has been considerable interest in the impact of mechanical stresses on the
thermodynamic state of glassy materials over the past quarter century—beginning with …

Volume recovery measurements have been used to study the physical aging behavior of a
polyetherimide. Isothermal aging temperatures near Tg were studied with aging times …

This article gives an overview of experimental results on dynamics in bulk glass-forming
molecular liquids. Rather than looking for phenomenology that is universal, in the sense that …

A large number of experimental results in the literature support and illuminate a model of
behavior of chains and chain segments in the amorphous phase of semicrystalline polymers …

A series of uniaxial cyclic tests were carried out on solid cylindrical specimens of an epoxy
resin, Epon 826/Epi‐Cure Curing Agent 9551. The focus of the study was to investigate time …
