Beschreibung:
Structure evolution in multicomponent polymer melts and in their network equivalents is investigated. In the first part, particle-based simulations reveal that on short length and time scales, the collective kinetics of structure formation and relaxation of polymeric systems is influenced by the sub-diffusive single-chain dynamics. D-RPA and D-SCFT are employed to describe the collective behavior in the simulation. D-RPA successfully captures the observed time evolution of density fluctuations on short time scales, whereas D-SCFT fails to provide an appropriate description on time scales mu...
