Abstract
The influence of solubilized benzene on the viscosity of polysoaps is explained on the basis of a simple association model
for the polysoap. This model assumes aggregation of the hydrophobic side chains into cylinders disposed along the chain backbone.
Modification of the interfacial energies of the domains by adsorption of the aromatic molecules leads to a non-monotonic behaviour
of the mean aggregate size, and a corresponding non-monotonic behaviour of the reduced viscosity of the polysoap solutions.
