## Abstract The Flory‐Huggins binary interaction parameter and its enthalpy and entropy parts were experimentally determined for polyelectrolyte hydrogels based on poly(acrylic) acid (PAAc) and poly(methacrylic) acid (PMAc) with various mono‐ and divalent counterions. It was shown that water is a p

Equations are derived for (dT/dq~)p and (dp/dgp)r along the cloud-point curves of solutions of heterogeneous polymers in a single solvent. It is shown that the extreme of the cloud-point curve (the precipitation threshold) can be calculated using these equations, The results of some model calculatio
