ABSTRACT OF THE DISCLOSURE A method for the production of new derivatives of water- soluble cellulose ethers by the reaction of 100 parts by weight of a water-soluble cellulose other with 3 to 30 parts by weight of C8-18 alkyl(ene) succinic acid anhydride, in the absence of water and under neutral or acid conditions at elevated temperature, until, in analytically detectable terms, 1 to 8% by weight, based on the cellulose ether, of alk(en)yl succinic acid has reacted with the cellulose molecule; the products of the method; and their use as thickeners for aqueous surfactant solutions, dye disper- sions, and for hydraulically setting building materials or their use as protective colloids or emulsifiers in the suspension poly- merization of water-insoluble monomers in aqueous phase.
