Chain diffusion is widely existed in the injection molding, welding, and blending of polymer materials. Dynamic rheological technique has been proved to be a very sensitive method for studying the chain diffusion at the polymer/polymer interface. This paper gives a brief introduction of the principle and methodology of dynamic rheological technique and its application on the study of polymer/polymer chain diffusion. Influence of the initial chain-end distribution at the surface before contact on the diffusion mechanism, numberization of asymmetric polymer/polymer interface, mutual diffusion of asymmetric polymer/polymer, effect of molecular weight polydispersity on diffusion at polymer/polymer interface, coupling between flow and diffusion at polymer/polymer interfaces, as well as rheological study on interdiffusion and reaction at polymer/polymer interface in recent years are discussed. Finally, a simple review about application of dynamic rheological technique on interdiffusion at polymer/polymer interface is made.
