| Abstract: | A series of superabsorbent polymers based on sodium acrylate,sodium acrylamido tertiary butyl sulfonic acid and acrylamide was synthesized by inverse suspension polymerization using sorbitan monostearate as the dispersant,cyclohexane as the organic phase,N,N-methylene-bisacrylamide as the crosslinking agent and ammonium persulfate as the initiator .In this paper,the relation between the water-absorbency of the copolymer and the composition of the copolymer,the amount of the crosslinking agent used and the degree of neutralization were investigated.Results show that the water absorbency in various solutions for the copolymeric gel is enhanced by the addition of the acrylamido tertiary butyl sulfonic acid monomer into the copolymeric compositions.The effect of pH and thermal on the water absorbency of these gels are also investigated. |
