  We have developed a dynamic self-consistent field theory, without any
adjustable parameters, for unentangled polymer blends under shear. Our model
accounts for the interaction between polymers, and enables one to compute the
evolution of the local rheology, microstructure and the conformations of the
polymer chains under shear self-consistently. We use this model to study the
interfacial dynamics in sheared polymer blends and make a quantitative
comparison between this model and Molecular Dynamics simulations. We find good
agreement between the two methods.
