abstract = {The aqueous associating solution poly(ethylene oxide) (PEO)
of molar mass between 0.45 and 280 kDa was studied with
small-angle neutron scattering (SANS) near their critical
concentration in a temperature interval from 11.8 to 95.7
°C. SANS measures thermal concentration fluctuations whose
susceptibility and correlation length identified mean-field,
3D-Ising, and tricritical Θ-point critical behavior.
Scaling laws of the critical amplitudes of susceptibility
and correlation length were observed for the samples obeying
3D-Ising and tricritical Θ-point behavior in agreement with
the predicted ones for nonassociating semidilute solutions.
On the other hand, chain conformation is different for both
classes of criticality and is attributed to the concentrated
and semidilute regime of the phase diagram. In the
concentrated regime the chains are slightly more compacted
than Gaussian coils. However, all PEO solutions approach
ideal chain conformation at the Θ-temperature. A small
amount of PEO of the order of 10–5 is forming compact PEO
aggregates.},
