Dynamic density functional theory for entangled polymer mixtures*

  The dynamic density functional (DDF) theory is an efficient method to

 study the dynamic evolution of inhomogeneous polymer and block

 copolymer melts. It builds on the self-consistent field (SCF) theory,

 one of the most successful mean-field theories for such polymer 

 systems at equilibrium.  We have recently developed an approach to

  systematically construct DDF theories from microscopic reference

 simulation trajectories. Using this method, to develop a DDF theory

 for entangled polymer mixtures.  We discuss the crossover from the

 Rouse to the reptation regime, and the impact of entanglements on the

 ordering kinetics of copolymers and the demixing dynamics of

 homopolymer blends.
