Interpenetrating hydrogel network has been synthesized from gelatin an
d polyacrylamide by cross-linking with their respective cross-linking
agents. The swelling behavior of this Interpenetrating polymer network
(IPN) system was analyzed in water and in citric acid-phosphate buffe
r solution at various pH. The effect of temperature on swelling behavi
or of these gels has been analyzed by. variation from 25 to 60-degrees
-C at physiological pH. The drug release behavior of these gels was al
so analyzed with temperature variation at physiological pH. (C) 1994 J
