ABSTRACT:
The molecule of the new urethanes contains an aliphatic fluoroalcohol, an isocyanate and an aromatic dihydroxy, diamino, aminohydroxy, aminocarboxy or hydroxycarboxy compound. They are prepared by reacting an aliphatic fluoroalcohol with a diisocyanate or triisocyanate to give the fluoroalcohol/isocyanate adduct and by reacting this adduct with said aromatic compound to give the desired urethanes composed of an aliphatic fluoroalcohol, an isocyanate and the bifunctional aromatic compound mentioned, and also be reacting a urethane of this type which also carries an active hydrogen atom on the bifunctional aromatic compound, with an isocyanate compound containing one or more isocyanate groups. The new urethanes are preferably used for imparting an oleophobic and hydrophobic finish to textiles and leather.
