| Abstract: | The starch-g-acrylic was synthesized with soluble starch containing a part of precrosslinked starch and acrylic,then starch-g-acrylic/PAM super absorbent resin was prepared by inverse suspension polymerization.The influence of starch amount,initiator and cross-linking agent on absorbability were analyzed.The results indicated that when the amount of starch,the initiator mixture(APS and CAN) and crosslinking agent were 2.5 g,0.02 mmol and 0.1%,respectively,absorbability of starch-acrylic/PAM resin was the highest,and the absorbency rate test showed the earlier absorbency rate was high and absorbence equilibrium could reach in 20 min. |
