Effects of chain stiffness on the breakdown of the Cox-Merz rule in linear and ring polymer melts

Keishin Tsujino, Yuhi Sakamaki, Shota Goto +2

The Cox-Merz rule is an empirical relation between the magnitude of the complex viscosity, $|{\eta }^{\ast }(\omega )|$, obtained from linear viscoelasticity, and the steady-shear viscosit…
