• Phase transition
• Aqueous polymer solution
• Hydrogel
• NMR

The use of NMR spectroscopy in investigations of phase transitions in aqueous polymer solutions and gels is reviewed. Results on this subject as obtained mostly for thermoresponsive polymers (e.g., poly(N-isopropylacrylamide) and its copolymers, poly(N-isopropylmethacrylamide) and its copolymers, poly(vinyl methyl ether)) from temperature dependences of (1)H and (13)C NMR spectra, spin-lattice and spin-spin relaxation times, diffusion coefficients and NMR images are discussed.
