| titleOfInvention | Process for production of water-absorbable resin |
| abstract | The present invention relates to a method for producing an water absorbent resin comprising at least two stages of reversed phase suspension polymerization, wherein the odor derived from a raw material component, in particular a petroleum hydrocarbon dispersion medium, And a water absorbent resin obtained by the method. More particularly, the present invention relates to a method for producing an water absorbent resin by at least two stages of reversed-phase suspension polymerization, wherein the polymerization of the first stage of at least two stages of reversed-phase suspension polymerization comprises (A) A water-soluble ethylenically unsaturated monomer aqueous solution is firstly dispersed in a petroleum hydrocarbon dispersion medium in which a hydrophobic polymeric dispersant is dissolved or dispersed in the presence of a surfactant in the absence of a surfactant, and then (B) a surfactant is added to the dispersion to obtain a secondary dispersion (C) a step of carrying out polymerization using a water-soluble radical polymerization initiator to obtain an absorbent resin as hydrous gelatinous particles dispersed in the petroleum hydrocarbon dispersion medium, and Thereby obtaining the water absorbent resin. |
