The formation of interface from an initial sharp interface in polydisperseA/B blends is studied using the external potential dynamic method. The presentmodel is a nonlocal coupling model as we take into account the correlationbetween segments in a single chain. The correlation is approximately expressedby Debye function and the diffusion dynamics are based on the Rouse chainmodel. The chain length distribution is described by the continuous Schulzdistribution. Our numerical calculation indicates that the broadening ofinterface with respect to time obeys a power law at early times, and the powerlaw indexes are the same for both monodisperse and polydisperse blend. Thepower law index is larger than that in the local coupling model. However thereis not a unified scaling form of the broadening of the interface width if onlythe interfacial width at equilibrium is taken into account as thecharacteristic length of the system, because the correlation makes an extracharacteristic length in the system, and the polydispersity is related to thislength.
