Abstract:
     This invention discloses a method for preparing acrylic-acid-type super absorbent resin by neutralization and crosslinking-copolymerization of acrylic acid and its salt. The initiator is a composite of redox initiators, and the crosslinker is a composite of two or three of (methyl) acrylic acid polyol ester, acrylamide and polyol ether. The super absorbent resin has such advantages as simple process, low cost, high absorption rate of physiological saline, and good properties.
