## Abstract It was found that the upper critical solution temperature (UCST) of poly(acrylic acid‐__co__‐acrylamide) hydrogel decreases with increase in pH. The UCST of samples equilibrated in a buffer at pH 2.5 was 33.7 Β°C, whereas it shifted to below 0 Β°C when swollen in buffers above pH 10. FT‐I
