Figure 5.11 The lateral contraction of the polymer network, r P (l), versus polymer network stretching, l, with additional contraction due to hydrodynamic forces. The solid line corresponds to the jet profile r J (l). The initial volumetric concentrations of polymer are: f 0 = 0.1, 0.15, 0.2. Reprinted from Ref. [75] with permission of Springer.

A nonlinear response of the polymer network under stretching results in changes in its volume that, in turn, results in changes in local polymer concentration. Indeed, the volumetric polymer concentration in a stretched system is
