In this study, hydrogels of poly(acrylamide-co-2-hydroxyethyl methacrylate)
having different properties were prepared by a redox polymerization method
. Poly(ethylene glycol), PEG 4000 was included in the polymerization recipe
to increase the microporosity of the resultant polymeric structures. AAm/H
EMA hydrogels with different properties were obtained by changing initial A
Am/HEMA mole ratio, total monomer, PEG 4000 and crosslinker concentrations.
