Xyd Superabsorbent Synthetic And Performance Research And Applications

Supper absorbent resin XYD-1 which used acrylic acid and acrylamid as monomers and supper absorbent resin XYD-2 which used acrylic acid, acrylamid, 2- acrylamid- group 2-methyl propyl sodium sulphonate and dimethyl-diallylammonium chloride as monomers by radical polymerization as initiator with ammonium persulfate and sodium bisulphite and as cross linker with N,N-methene-di acrylamid by polimerization in aqueous solution have been respectively synthesized in the paper.The effects of initiator dosage, degree of neutralization acrylic acid by sodium hydroxide, cross linker dosage and amount of acrylamid being percent of acrylic acid on absorption water of Supper absorbent resin XYD-1 and the effects of initiator dosage, degree of neutralization acrylic acid by sodium hydroxide, cross linker dosage, amount of acrylamid being percent of acrylic acid, amount of 2- acrylamid- group 2-methyl propyl sodium sulphonate being percent of acrylic acid, amount of dimethyl-diallylammonium chloride being percent of acrylic acid and acrylic acid dosage on absorption water of Supper absorbent resin XYD-2 were respectively studied by evaluating of absorption ratio in deionized water and absorption salt ratio in 0.9% sodium chloride solution. The effects of synthesizing temperature, pH value, different solution and saft concentrations on absorption water ratio were discussed in this paper. Structure of the supper absorbent resin XYD-1 and XYD-2are verified by Infrared spectroscopy. Commercial solid products synthesized by XYD-1 formulation has bee used in profile control of polymer flooding in oil-field.
