METHOD FOR MANUFACTURING SUPER ABSORBENT POLY(VINYL ALCOHOL) MOLDING MATERIALS HARMLESS TO THE HUMAN BODY WHILE MAINTAINING PROPERTIES AND SHAPE STABILITY OF A POLY(VINYL ALCOHOL) RESIN

摘要

PURPOSE: A method for manufacturing the crosslinked poly(vinyl alcohol) molded materials is provided to prepare a super absorbent resin in which the absorption to water is 200% or greater while maintaining shape stability by irradiating ultraviolet rays to a poly(vinyl alcohol) molded material in which a photoinitiator is absorbed. ;CONSTITUTION: A method for manufacturing the crosslinked poly(vinyl alcohol) molded materials comprises the steps of: (i) dipping poly(vinyl alcohol) molded material in a photoinitiator aqueous solution and absorbing the photoinitiator to the PVA molded materials; and (ii) irradiating ultraviolet rays to the PVA molded materials in which the photoinitiator is absorbed. The photoinitiator is a water-soluble ketone compound.;COPYRIGHT KIPO 2011
