Changes in material during mixing

Even at the end of mixing, the system is not uniform and consists of parts having different viscoelastic history. The model described here represents only macroscopic changes. Microscopic change such as growth of bound rubber must be accommodated later. This type of phase-modelling is in progress in the field of polymer blends and a similar approach may be adopted here.
