| Abstract: | The high water - absorbing resin, i.e., poly (sodium acrylatea - crylamide - 2 - hydroxyethyl methacrylate), was prepared by inverse suspension copolymerization under the condition of using potassium persulfate as initiator, cyclohexane as the continuous phase, N, N - methylene - bisacrylamide as the crosslinking agent and mono - oc-tadecyl phosphate as the dispersant. The effects of the amount of the crosslinking agent, monomer composition and neutralization value of the acrylic acid as well as the concentration of electrolyte in the water on the water -absorption capacity of the copolyrner were studied. The absorption amount of the resin for deionizing water reached 2 000 g/g or more and for NaCl solution in concentration of 0.9% reached 100 g/g or more. |
