## Abstract Poly(acrylic acidβ__co__βacrylamide) (PAAAM) hydrogels have been prepared from partly neutralized acrylic acid (AA) and acrylamide (AM) by solution polymerization, and their absorbency and adsorption in both CuCl~2~ and FeCl~3~ solutions have been investigated. PAAAM hydrogels and their
## Abstract It was found that the upper critical solution temperature (UCST) of poly(acrylic acidβ__co__βacrylamide) 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. FTβI
