| Abstract: | The super absorbent resin was synthesized by inversed phase suspension polymerization of acrylic acid sodium acrylate, using miscella as dispersion phase, Span85 OP7 as dispersing agent, N,N methylene bis acrylamide as crosslinking agent and potassium persulfate sodium sulfite as redox initiators. The optimal reaction conditions were discussed. The products is uniform particles and easy to drying, its water absorption capacity is 1 250 g/g and 0.9% salt water absorption capacity is 110 g/g. |
| Keywords: | super absorbent resin inversed phase suspension polymerization acrylic acid sodium acrylate copolymer |
