(a) Storage modulus as a function of angular frequency at different isothermal conditions obtained from DMTA experiments and (b) master curves of storage and loss moduli shifted to a reference temperature of = 50°C. The solid line in the insert shows the calculated shift factors obtained from WLF approximation.
