    Abstract: A process for the production of super-absorbent polymers with a swelling capacity in water-containing liquids of up to 1,000 g/g in which aqueous emulsions of particularly high molecular weight polymers of acrylonitrile are partly hydrolyzed by reaction with aqueous solutions of alkali metal and/or alkaline earth metal hydroxides, the polymers are precipitated in powder form by addition of water-miscible organic solvents, separated off, dried and then optionally heated for a short time. The super-absorbent polymers are used as water-storing materials, for example in sanitary articles, in agriculture or in the sheathing of electrical cables.
