The superabsorbent polyacrylic acid/chitosan/montmorillonite(PAA/CTS/MMT) composite resin were synthesized by solution polymerization
and its structure was characterized by FTIR.The effects of the amount of initiator
crosslinker
montmorillonite and the mass ratio of the acrylic acid and chitosan on the absorbency of composite resin were investigated.The results show that the highest absorbencies of composite resin for distilled water and saline water are 425 times and 65 times
respectively.At this point
the mass ratio of AA and CTS is 10∶1;the amount of MMT is 2%;the amount of initiator and crosslinker reaches 3.2% and 0.16%
