|Title:||Swelling kinetics of poly(acrylamide)/poly(mono-n-alkyl itaconates) hydrogels|
Diaz De Apodaca, E.

|Abstract:||Hydrogels of mono-n-alkyl itaconate/N-acrylamide have been synthesised. The swelling process at three different pH values (acid, neutral and basic) has been studied. The experimental data indicate that our hydrogels follow second-order swelling kinetics. According to this, the kinetic constant, K?, and the swelling capacity at equilibrium, W?, have been calculated. The influence of the solvent pH and the molar mass of the mono-n-alkyl itaconate monomeric unit has been analysed. It seems that the general balance between the hydrogen bonding and the hydrophobic interactions regulates the swelling process of these hydrogels. © 1996 SCI.|
