## Key Results

The Brochard-Wyart "stem-and-flower" model posits that the relaxation of a tethered polymer under flow at intermediate velocities is described by

<math> L(t)-L_0 \propto \sqrt{\frac{kT}{\eta a} t} </math>

Where L(t) is the length at time t, <math>L_0</math> is the initial length, k is the Boltzmann constant, T is the absolute temperature, <math>\eta</math> is the viscosity of the solvent, and a is the persistence length.
