This paper briefly reviewed the dynamic rheological behavior of multiphase / multicomponent polymers. Breakdown of the time-temperature superposition principle in the long time range (terminal range) for those polymers Was discussed. The importance of using dynamic rheology measurements for characterizing phase-separation of multiphase/multicomponent polymers was emphatically evaluated.
