Steady state compliance Rouse model

Pig. 4.12 Steady-state compliance of nearly monodisperse polystyrene melts at 160°C. The dashed line represents the result of the Rouse model. Reproduced, with permission, from Ref. 11. 

Figure 5.12 Sketch of steady-state compliance versus molecular weight for samples of a monodisperse, linear polymer. Below the linear increase is in accord with the Rouse-Bueche model (Eq. 5.9), while above this critical molecular weight, a further increase is suppressed by entanglements (Eq. 5.10).
