Polystyrene (PS) samples carrying terminal or in-chain nitroxide spin labels have been blended with poly(vinyl methyl ether) (PVME) in varying proportions and their electron spin resonance (ESR) spectra recorded over a range of temperatures. The spectra are mainly of the slow-motion type but reÑect
## 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
