15. Below Tg: secondary relaxations
Figure

shows the evolution of the dielectric loss factor
of amorphous maltitol as a function of temperature, for several frequencies from 100 to 200 kHz. The temperatures cover a range on either side of T

. For T > T
g
, we note the presence of the α relaxation peak, whose temperature at the peak...
