1H and 13C NMR spectroscopies were applied to investigate phase separation in solutions of poly(N-isopropylmethacrylamide) (PIPMAm) in D2O/ethanol (EtOH) mixtures induced by solvent composition (cononsolvency) and temperature. Differences in mesoglobules formed during the phase separation induced by cononsolvency and temperature were found. While for temperature-induced phase separation there is a portion of EtOH molecules bound in mesoglobules, virtually no bound EtOH was detected for mesoglobules formed as a consequence of the cononsolvency.
