Özet

Swollen hydrogels were prepared by gamma-radiation copolymerization of N-vinyl-2 pyrrolidone and acrylonitrile. The influence of radiation dose and feed composition on the swelling properties, diffusional behavior of water and diffusion coefficients of the hydrogel systems were examined. N-vinyl-2-pyrrolidone/acrylonitrile hydrogels were swollen in the range 50-850%. Water diffusion to the hydrogels generally was a non-Fickian type diffusion.
