- Abstract
- Super water-retainer hydrogels in the rod form were prepared by
copolymerization of acrylamide and succinic acid monomers with gamma
radiation. Swelling took place in water at 25 degrees C and was followed by
weighing. The influence of dose and relative content of succinic acid on the
swelling properties, diffusional behavior of water, diffusion coefficients
and network properties of hydrogel systems were examined. Acrylamide/succinic
acid hydrogels were swollen in the range of 750-960%, while polyacrylamide
hydrogels at 650-700%. Water diffusion into hydrogels was non-fickian type
diffusion. Diffusion coefficients of acrylamide/succinic acid hydrogels were
calculated by the short time approximation as 4.6 x 10(-7)-7.9 x 10(-7)
cm(2)s(-1). [References: 59]
