| Abstract: | A super-water-absorbent resin was synthesized by the method of microwave polymerization using N,N'-methylene-bis-acylamide as a crosslinking agent and ammonium persulfate as an initiator at one step.The influence of mole ratio of acrylamide(AM)to acrylic acid(AA),the pH of reaction system,the amount of crosslinking agent and initiator,and the power and time of microwave was investigated and optimized.The water absorbing capacity of the obtained ammonium polyacrylate is best at 930g/g?SEM and FTIR were also used to characterize the product. |
