Synthetic and Performance Research on the New Type Hydrogel with Acrylic Acid and Acrylamide Unit

Abstract:

High acrylamide content hydrogel was synthesized under mild condition through a copolymerization reaction between acrylic acid (AA) and acrylamide (AM) using N, N-methylenebis-acrylamide as crosslinker and potassium persulfate combination with sodium sulfite as initiator in aqueous solution. The factors with influence on water absorbency performance including molar ratio of AM to AA, neutralization degree, content of crosslinker and initiator were investigated. Further orthogonal experiment with four factors and three levels were employed to determine the optimized conditions, in which not only water absorbency but also gel strength was taken into account.
