Sodium lignosulphonate and acrylic acid as raw materials,water retention agent was synthesized by aqueous solution polymerization ( superabsorbent polymers) . Infrared spectra of samples were charac-terized. Study the influence of synthetic reaction and performance factors. Optimum process conditions were obtained:the content of the sodium ligninsulfonate is found to be 26. 54%,the polymerization tem-perature is found to be 72~78 ℃;the neutralization degree of acrylic acid is found to be 42% ~47%;the crosslinker concentration and initiator concentration are found to be about 0 . 16% ~0 . 18% and 5. 45% ~6. 33%,respectively. Maximum water absorbency is 875 g/g.
