## Abstract **Summary:** The thermosensitive phase‐separation of poly(vinyl methyl ether) in water has been investigated by micro‐Raman spectroscopy in the presence of tetraalkylammonium bromides. The equilibrium distribution of both polymer and salts to the polymer‐rich and solvent‐rich phases was

The behaviour of hyaluronic acid (Hyal) and sulfated hyaluronic acid (HyalS) in aqueous solution was investigated in terms of protonation and complex formation by thermodynamic and spectroscopic techniques. The presence of the scarcely protonable sulfate groups in the polymer chain provided the Hyal
