| Research Abstract |
In miscible polymer blends, the component concentration still fluctuates. The effects of this dynamic heterogeneity on the global dynamics of the component chains therein were investigated with viscoelastic and dielectric methods. It turned out that the dynamic heterogeneity is effectively quenched in the time scale of the relaxation of the fast component thereby providing this component with the thermo-rheological complexity and masking its entanglement plateau. The corresponding behavior was found also for block copolymers in a miscible state.
