MODIFIED CELLULOSE ETHERS AND THE USE THEREOF IN DISPERSION PAINTS

摘要

HOE 90/F 268 : Modified cellulose ethers and the use thereof in dispersion paints The invention relates to water-soluble cellulose ethers containing at least one fluorine-free radical attached via an ether link and selected from the group hydroxyethyl, hydroxypropyl, methyl, ethyl and carboxymethyl, and a hydrophobic substituent which comprises one fluorine-containing alkyl radical of 3 to 24, in particular 5 to 18, carbon atoms, the fluorine content being 0.05 to 5, in particular 0.1 to 1% by weight, based on the dry weight of the cellulose ether. These cellulose ethers are suitable for use as thickeners in dispersion paints.
