A series of hydrophobic sodium poly(styrene-co-styrene sulfonate) of
different charge fractions has been studied by static light scattering
in the thermodynamic limit. In the examined concentration range
(, in monomers), the solutions show an ideal gas behaviour.
A quantitative comparison with previous osmotic pressure measurements reveals
the existence of a strong variation of the polarizability, which is
related to a change of local chain conformation.
This result can be interpreted in terms of the globular instability
model for hydrophobic polyelectrolytes (pearl necklace model).
