Synthesis of Super Absorbent Resin from Starch/Bentonite

摘要：

　　The compound super absorbent resin was synthesized by starch, bentonite, acrylic acid and acrylamide, using microwave irradiation.Some key factors affecting the solution absorbency of the polymer such as the amount of bentonite, acrylamide, initiator and cross-linking agent have been discussed.The results showed that the optimal reaction conditions of cross-linking agent, initiator, neutralization degree, bentonite, phosphate starch are 0.045%, 0.32%, 70%, 10%, 3% when the weight ratio of acrylic acid and acrylamide was 2:1, the microwave power was 800W, the radiation time was 15min.Under the conditions, the pure water absorption rate of super absorbent resin was up to 796g/g.when the weight ratio of acrylic acid and acrylamide was 1:1, the absorption rate of 0.9% NaCl was 95g/g.
