Abstract: A series of thermoresponsive hydrogels based on copolymers of 2-methoxyethylacrylate with acrylamide or N,N-dimethylacrylamide were prepared by radiation-induced polymerization in dimethylformamide solution in the presence of a crosslinking agent. The swelling behaviour of the hydrogels was studied by immersing the polymer samples in water at 5°C, 10°C and 37°C. The data were found to satisfactorily fit Fick's law with a constant diffusion coefficient. The results indicate that the swelling ratio increases with increasing the content of the hydrophilic monomers in the hydrogels and at the same time the equilibrium swelling time decreases. The effect of temperature on water transport mechanism was observed. © 2001 Elsevier Science Ltd. All rights reserved.
