The factors that influence on liquid absorbency rate of the super absorbent resinwere discussed, including m icrowave power, reaction tmi e, monomer ratio, neutralization degree of , initiator dosage, and crosslinking agent dosage. The structure of the super absorbent resin was characterized by themethod of IR. It just needed 30 s to preparation the super absorbent resin. Its liquid absorbency ratewas about 1 580 g/g and 170 g/g in purified water and 0. 9% NaCl solution.
