| titleOfInvention | Processes for producing water-absorbing resin |
| abstract | Using a low-cost maleic acid derivative as a raw material, a method for producing a super absorbent crosslinked polymer having excellent absorbency and biodegradability, a method for producing a biodegradable superabsorbent crosslinked polymer by a simpler reaction process, and further, a superabsorbent crosslinked polymer is contained. In providing a method for producing a super absorbent polymer, the method is a step 1, a step of simultaneously performing a polymerization reaction and a crosslinking reaction at 100 to 350 ℃ in the reaction system to obtain a crosslinked polymer, and step 2, in the step 1 It characterized by including the process of hydrolyzing the obtained crosslinked polymer and manufacturing a superabsorbent crosslinked polymer. In addition, the reaction system includes (A) (a-1) maleic anhydride and ammonia, (a-2) dicarboxylic acid and ammonia having four carbon atoms, (a-3) monoammonium salt of dicarboxylic acid having four carbon atoms, and At least one monomer selected from the group consisting of diammonium salts, (a-4) monoamides and / or diamides of dicarboxylic acids having four carbon atoms and (a-5) imides having four carbon atoms; (B) a crosslinking agent and (C) an acid. |
