<p><P>PROBLEM TO BE SOLVED: To provide a method for producing an absorptive resin particles including a material originating from vegetables and having excellent absorption performance. <P>SOLUTION: The method for producing the absorptive resin particles includes: a step (1) for copolymerizing monomers including a water-soluble vinyl monomer (a1) and/or a hydrolyzable vinyl monomer (a2) and a crosslinking agent (a3) as indispensable constituent monomers (a) to obtain a crossliked polymer (A) and then mixing the crosslinked polymer (A) and a cellulose (B) to obtain a crosslinked polymer/cellulose composite gel (A/B); or a step (2) for mixing the monomers including the water-soluble vinyl monomer (a1) and/or the hydrolyzable vinyl monomer (a2) and the crosslinking agent (a3) as indispensable constituent monomers (a) and the cellulose (B) with each other and then copolymerizing these to obtain a crosslinked polymer/cellulose composite gel (A/B); and a step (3) for subjecting the crosslinked polymer/cellulose composite gel (A/B) to after-treatment to obtain the absorptive resin particles. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
