Micro-Rheological Modelling

The Kinetic Theory of Polymeric Liquids

All the complexity of the rheological behaviour of polymeric materials is ultimately rooted in their molecular structure or, in the case of suspensions, blends, block copolymers, or other complex materials, is due to the “structure” of the material at the scale of, say, 1 µm. Thus a valuable alternative to the classical approach to rheology, originally founded in continuum mechanics, is one which starts from a consideration of the micro-structure of the system, and attempts to model those structural features which are most likely to be important in determining the rheological behaviour which is observed macroscopically. This is, generally speaking, the approach known as micro-rheological modelling, though in the present context only the case of solutions and melts of ordinary polymers will be considered, for which the names of “molecular modelling” or “molecular theories” are more often employed.
