Method for production of water absorbent resin.

摘要

The present invention is a method for the production of a water absorbent resin, which comprises preparing a monomer component having an ability to form a cross-linked structure, having an acid group-containing monomer content of at least 50 mol%, and having 10 to 50mol% of the acid group-containing monomer neutralised. This is subjected to aqueous solution polymerisation to form a hydrated gel polymer within a reaction vessel having a plurality of rotary shafts each fitted with stirring blades.
