- Abstract
- Acrylamide-crotonic acid hydrogels in the form of rods are prepared by
gamma-irradiation of quaternary mixtures of acrylamide-crotonic acid-crosslinker-water
with 2.6 and 5.2 kGy gamma-rays. The influence of the applied dose, the
relative content of crotonic acid and crosslinkers such as ethylene glycol
dimethacrylate, 1.4 butanediol dimethacrylate and N,N'
methylenebisacrylamide on the swelling properties of the gel, the
diffusional behaviour of water, the diffusion coefficient: and the network
parameters of hydrogel systems are examined. Acrylamide-crotonic acid
hydrogels containing various crosslinkers had a maximum swelling in the
range 240-850 %. Water diffusion to hydrogels was non-Fickian. The diffusion
coefficients varied between 4.6 x 10(-7) and 9.1 x 10(-7) cm(2) s(-1). [References:
