Abstract

 In this study, a HYDROGEL composed of ACRYLAMIDE (AAm) with N-VINYLIMIDAZOLE (NVI) as co-monomer, with a cross-linker such as N, N’ Methylenebisacrylamide and potassium peroxodisulfate as an initiator solution was prepared. Poly (AAm/NVI) HYDROGELs were synthesized by free radical solution polymerization. SWELLING experiments were performed in water at 25oC, gravimetrically. Here, it was of interest to increase the water absorption capacity of AAm HYDROGELs with add VI. AAm is a highly hydrophilic monomer, and VI monomer is neutral. The one purpose of this study is to combine both monomers in one polymer. In this respect, a series of HYDROGELs was synthesized by changing the content of AAm and VI. Then, some SWELLING of these HYDROGELs was studied in water.
