Process for the continuous production of superabsorbent polymers from PAN emulsions |
| abstract |
A process for producing a superabsorbent polymer is described. The process that entails a continuous hydrolysis of an aqueous emulsion of crosslinked or uncrosslinked polyacrylonitrile in the form of fine particles is carried out in a cascade of stirred tanks. The reaction with alkali-hydroxide solution an aqueous-alcoholic medium at 60 to 100° C. yields polymers that are suitable for the preparation of hygiene products, water-storing materials in agriculture, and sheathing of electrical cables. |
