| titleOfInvention | Continuous process for production of superabsorbent polymer |
| abstract | The present invention relates to a continuous process for the production of a superabsorbent polymer comprising: (a) providing an acidic liquid aqueous monomer mixture containing dissolved oxygen, whereby the monomers are selected to provide after polymerization a superabsorbent polymer, (b) continuously feeding said aqueous monomer mixture to a reactor, (c) introducing a source of carbonate or hydrogen carbonate into said aqueous monomer mixture prior to entry into the reactor thereby forming a gas phase comprising carbon dioxide and at least a part of said dissolved oxygen, said gas phase being dispersed in the liquid phase, (d) subjecting the gas/liquid mixture to at least partial phase separation immediately prior to or after entry into the reactor and at least partially removing the separated gaseous phase, (e); subjecting the liquid phase in the reactor to free-radical polymerization to obtain the superabsorbent polymer, and (f) continuously removing the superabsorbent polymer from the reactor. |
