Formation of compact globular‐like structures at temperatures above the phase transition suggests that NMR spectra of the systems will be affected in direction to NMR spectra of solid‐like systems. Temperature dependences of integrated intensities were often used for characterization of the phase transition in number of thermoresponsive systems. The power of NMR spectroscopy in investigation of temperature‐induced phase transition in solutions of multicomponent polymer systems consists in its ability to provide quantitative information on the behavior of individual polymer components separately. A detailed knowledge of interactions in systems containing various low‐molecular‐weight additives can be important especially in connection with the development of drug release systems based on thermoresponsive polymers. NMR spectroscopy, including relaxation and diffusion measurements, provides also important information on the behavior of water molecules at temperature‐induced phase transition.
