[ Objective ] The research aimed to provide the technical basis for the modification development and utilization of potato starch and preparing absorbent materials. [ Method ] Potato starch and. acrylate were used as materials to prepare super absorbent resin by grafting. The effects of main conditions including material proportion, acrylate neutralization degree, initiator concentration and reaction temperature on the resin properties were discussod. The best reaction parameters were confirmed. [ Result] The potato starch grafting acrylate had a higher water ab- sorptiveness and moisture retention. [ Conclusion] The preparation of potato starch grafting acrylate super absorbent resin had simple technologies, low cost, convenient materials and wide application foreground.
