Abstract: The novel urethanes correspond to the formula I below in which a denotes a number from 5 to 17 and b denotes a number from 1 to 7. These urethanes are prepared by reacting the corresponding perfluoroalkylethanol/epichlorohydrin adducts with toluelene diisocyanates. The novel aqueous dispersions are essentially composed of the novel urethanes, cationic or betaine emulsifiers and non-ionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic acid esters and alkanediols or polyalkanediols which can be etherified on one or both sides, in water. The novel urethanes and the novel aqueous dispersions are used to impart an oleophobic and hydrophobic finish to textiles, leather and furs. They are also suitable for the treatment of unpainted timber, for example unpainted furniture.

Abstract: The novel urethanes correspond to the formula I below in which a denotes a number from 5 to 17 and b denotes a number from 1 to 7. These urethanes are prepared by reaction of the corresponding perfluoroalkylethanol-epichlorohydrin adducts with toluylene diisocyanates. The novel aqueous dispersions consist essentially of the novel urethanes, cationic or betainic and non-ionic emulsifiers, water-insoluble carboxylic acid and/or dicarboxylic acid esters and alkanediols or polyalkanediols, which can be mono- or dietherified, in water. The novel urethanes and the novel aqueous dispersions are used for the oleophobic and hydrophobic finishing of textiles, leather and unvarnished wood, for example unvarnished furniture.
