Abstract: This invention relates to an improvement in the process for the production of water-adsorbing, but at least partially water-insoluble, cellulose ethers in which cellulose is alkalized in a liquid reaction medium and etherified in a manner such that by etherification only an at least largely water-soluble carboxymethyl cellulose, carboxymethyl hydroxyethyl cellulose, hydroxyethyl cellulose or methyl hydroxyethyl cellulose is produced, and in which the cellulose is reacted in an alkaline reaction medium before, during, or after the etherification with a cross-linking agent which is polyfunctional towards cellulose and selected from the group consisting of acrylamido methylene chloroacetamide, dichloroacetic acid, phosphorous oxychloride, or a compound in which at least two groups functional towards cellulose are the acrylamido group the chloroazomethine group the allyloxy azomethine group the improvement comprising effecting alkalization, etherification, and cross-linking in a liquid reaction medium other than isopropyl alcohol.
