What is the origin of the anomalous up-turn of reduced viscosity of polyelectrolyte solutions ?

It has been explained as:  “Chain expansion effect due to intra-molecular electrostatic repulsion”

It is partly, “yes”.

Then, why ridged spherical polyelectrolytes also show the up-turn ?

There must be a common origin !
