“…truerightτ=τ0prefixexp()EαknormalBTwhere k B is the Boltzmann constant and E a is the apparent activation energy. The linear relationship between τ max and 1/ T is a typical behavior for the local dynamics of amorphous, semicrystalline, and thermoset polymers . Clearly, insignificant changes in the dynamics of the two local relaxation processes were observed with changing sample composition.…”

“…Compared with DMA, BDRS covers a much wider range of frequencies suitable for observing the relaxation phenomena mentioned above in a single‐frequency scan measurement based on the nature of the material and the temperature range of each relaxation process. Recently, we have used this BDRS technique to study the miscibility of polymer blends, the kinetics of phase separation, and crystallization kinetics in amorphous/crystalline mixtures . BDRS is also a very sensitive technique to monitor any change in the molecular dynamics and dynamical constraints associated with thermoset formation, branching, crosslinking density, and the corresponding bulk properties.…”

“…As reported in the literature [32,33], b processes are associated with local motion determined by rotational or vibrational fluctuations of side groups or parts of them. In addition, assignment of the molecular motions associated with the midtemperature range relaxation is attributed to the b relaxation mode [34].…”
