| Abstract: | A kind of novel high water-absorbing resin based on acrylic acid, acrylamide and methyl methacrylate was prepared by inverse suspension copolymerization. The relation between the water-absorption praperty of the copolymer and the compositon of the copolymer, the amount of crosslinking agent used and the degree of neutralization was studied in detail. The absorption amount of the copolymer resin is more than 2000 g/g and 130 g/g in case of deionizing water and 0.9 % NaCl solution, respectively. |
