Relation between mobility factor and diffusion factor for thermoset cure

Network Formation and Physical Properties of Epoxy Resins for Future Practical Applications

“…Actually, the gel point was determined to be the time at which the tan δ curves acquired at various frequencies intersect one another. , Here, it is noteworthy that the decrease in G ″ with increasing time is an indication of vitrification, where the segments are frozen in terms of mobility, leading to the lesser contribution of the energy dissipation. , In fact, when the curing temperature is substantially higher than the T g of the system, no decrease in G ″ is observed during the curing process . The T g value, which generally increases with increasing curing time, can be determined as a heat capacity change detected by temperature-modulated differential scanning calorimetry (TMDSC). , …”
