  • Salts, containing fluoroalkyl groups, of beta-alkylamino-propionic acid esters, a process for their synthesis and their use for the production of aqueous polyacrylate dispersions containing fluoroalkyl groups
    Patent number: 4780244
    Abstract: Compound of the formula ##STR1## in which n denotes a number from 4 to 12, preferably 6 to 8, R.sub.1 denotes hydrogen or methyl, preferably hydrogen, R.sub.2 and R.sub.3 denote C.sub.1 -C.sub.6 -alkyl, preferably propyl or butyl, and X denotes halogen, HSO.sub.4 or anions of organic acids having 1 to 4 carbon atoms, or CH.sub.3 OSO.sub.3, and preferably denotes chlorine.These compounds are used on their own or together with non-ionic surfactants as an emulsifier for the production of aqueous polymer dispersions of fluorine-containing acrylic acid esters. Polymer dispersions of this type, formed from fluorine-containing acrylic acid esters, are used for imparting an oleophobic and hydrophobic finish to textile materials.
    Type: Grant
    Filed: January 20, 1987
    Date of Patent: October 25, 1988
    Assignee: Hoechst Aktiengesellschaft
    Inventors: Herbert Ramloch, Manfred Seidel, Joachim Lause, Karl Waldmann
