We investigated the hydration and swelling properties of poly(N-isopropylacrylamide) and poly(N-isopropylacrylamide)-poly(N,N-diethylacrylamide) derived microgels by Fourier transform infrared-(FTIR-) spectroscopy in a wide region of the temperatureepressure plane. These systems are known to show a
## Abstract Coil‐globule transition of poly(__N__‐tert‐butylacrylamide‐__co__‐acrylamide) P(NTBAM‐__co__‐AM) copolymers is investigated in the aqueous solution and in the mixture of water–methanol by micro ATR‐FTIR spectroscopy technique. In this study the microstructure and its changes in the hydr
