- Abstract
- In this study, highly swollen acrylamide/crotonic acid hydrogels tilt a
rod form) containing some inorganic salts such as ammonium nitrate potassium
nitrate and ammonium sulphate used as fertilizer, an agricultural drug such
as Dalapon (sodium 2,2-dichloropropionate) and two crosslinkers such as
ethylene glycol dimethacrylate and 1,4-butandiol dimethacrylate were
prepared by copolymerization of acrylamide and crotonic acid with gamma-radiation.
As a result of swelling tests, the influence of gamma-ray dose and relative
content of crotonic acid on the swelling properties, the diffusional
behavior of water, diffusion coefficients and network properties of the
hydrogel systems were examined. Acrylamine/crotonic acid hydrogels
containing these salts and agricultural drug were swollen in the range
2045-400% in water, while polyacrylamide hydrogels swelled in the range
660-700%. Water intake of hydrogels followed a nonFickian-type diffusion.
